The Glock 17 Gen 5 has established itself as a go-to handgun for many firearms enthusiasts thanks to its reliable performance, user-friendly operation, and impressive accuracy. Despite its high-quality design, there is always room for upgrades that can further improve its performance and accuracy. One essential element of any handgun is the barrel, which dictates the bullet’s path as it exits the firearm. By upgrading the Glock 17 Gen 5’s barrel, you can achieve a noticeable improvement in performance and accuracy.

5 Benefits of Upgrading Your Barrel

Upgrading the barrel of your Glock 17 Gen 5 can offer a range of benefits that can improve its performance and enhance your shooting experience. Here are some of the top benefits you can expect:

Improved accuracy: One of the most significant benefits of upgrading your Glock 17 Gen 5 barrel is improved accuracy. A high-quality barrel will have a tighter bore and more precise rifling, which can help stabilize the bullet and keep it on target. This can be especially beneficial if you’re using your Glock 17 Gen 5 for competitive shooting or self-defense purposes, where accuracy is critical.

Increased range: Another advantage of upgrading your Glock 17 Gen 5 barrel is increased range. A high-quality barrel can improve the bullet’s velocity, allowing it to travel further and hit targets at longer distances. This can be particularly useful for outdoor shooting or hunting.

Enhanced safety features: Some aftermarket barrels for the Glock 17 Gen 5 may come with enhanced safety features, such as improved feed ramps or a tighter chamber. These safety features can improve reliability and reduce the risk of malfunctions or misfires.

Increased Reliability: Aftermarket barrels are often made with higher-quality materials than stock barrels, such as stainless steel or titanium. These materials can be more durable and resistant to wear and tear than a stock barrel, reducing the risk of failure or malfunction. Also, most aftermarket barrels are precision-machined to tighter tolerances, which makes the fit and function more consistent.

Ammunition Compatibility: Another factor that can contribute to increased reliability is the ability of aftermarket barrels to shoot a wider range of ammunition types. The stock barrel of the Glock 17 Gen 5 is designed to handle a specific type of ammunition, and using different types can sometimes lead to jams or malfunctions. However, many aftermarket barrels are designed to handle a wider variety of ammunition types, making them more versatile and reliable in a wider range of situations.

Glock 17 Gen 5 Barrel Differences

The Glock 17 Gen 5 features a switch to Glock 19 locking geometry. 

While the Gen 4 and Gen 5 19 barrels have different geometries, the Gen 5 barrels do away with the slope at the barrel hood and instead go to the simple right angles that the 17/34 have always had, similar to most G19 Gen 1-4 aftermarket barrels. 

Due to the shared locking block, a Gen 5 17 barrel can theoretically be used in a Gen 5 19. 

However, it’s important to note that Gen 1-4 17 barrels are not compatible with a Gen 5 17.

Even though Glock improved the Glock 17 Gen 5 OEM barrels to make them more accurate (hence the name “Marksman Barrel”), there is still room for improvement.

The optimized match barrels from Faxon Firearms have been redesigned to work better and with Gen 5 guns.

These Glock 17 Gen 5 barrels have been redesigned for improved performance and Gen 5 compatibility. A recessed target crown, a new match chamber, and a stylized barrel hood with engravings for caliber and model are some of the new features.

The proprietary broach-cut 1 in 14” left-hand twist rifling was developed to create the most accurate Glock aftermarket barrel available, and testing confirms a significant increase in accuracy over factory barrels in all standard bullet weights.

Manufactured from 416R stainless steel, which is an ideal material for making match-grade barrels because the material allows for the precise cutting of chambers and rifling, which results in a more accurate barrel.

Glock17 Gen 5 Threaded Barrel and Compensator

The threaded barrel and compensator work together to enhance the accuracy and stability of the Glock 17 Gen 5. The compensator shown here for the Glock 17 Gen 5 called EXOS has a unique design with an angled front port and a single chamber.

This design helps to decrease the movement of the muzzle by reducing both the upward and sideward recoil, resulting in improved accuracy from shot to shot.

Muzzle flip reduction is baked into the DNA of Faxon EXOS compensators.

Upgrading your Glock 17 Gen 5 barrel can be a game changer for anyone who wants to take their firearm’s performance to the next level. 

With improved accuracy, increased range, reduced recoil and muzzle rise, enhanced safety features, and increased reliability, the benefits of upgrading your barrel are undeniable.

With the right barrel, you can unlock your firearm’s full potential and take your skills to the next level.

SilencerCo is on a mission. A mission to do it better. Do what better? Good question. Let’s look at that. First and foremost, SilencerCo strives to make better suppressors and suppressor accessories. That’s fine, but one could easily say the same for many companies that make quality products. What matters here is how SilencerCo does it.

SilencerCo lives by what they call “The Three Ps,” People, Passion, and Precision. The Three Ps are the road map to accomplish their mission of doing it better. Let’s break down how that philosophy works.

People

We often hear companies say that they put the customer first. A common customer service maxim says that “the customer is always right,” even though any honest person knows that’s untrue. SilencerCo takes a somewhat different approach to outstanding customer service: they put their employees first.

The idea is that happy employees, people who genuinely like, or even love, their jobs, will strive to do their best every day. That means better, more consistent product lines, more innovation, faster, friendlier service, and a great experience for everyone involved. In short, people who take pride in their work want to do things the right way. Everyone wins. That’s what SilencerCo aims for every day.

So, how do they do that? After all, a job is a job, and most folks would rather be doing other things. We’ve all been there. SilencerCo recognizes all that but continues to take steps toward improving their employees’ experience. Let’s look at a few of those.

Automation 

SilencerCo is investing heavily in robotics to aid the manufacturing process. Usually, automation means real people lose their jobs because they’ve been replaced. Not so at SilencerCo. Founder and CEO Jonathan Shults told us that “By introducing higher levels of automation into our production processes we are creating greater efficiency for our company and more enjoyable jobs for our employees. We are automating the parts of manufacturing that are mundane and tedious. Employees will work in conjunction with these new automations in a way that allows them to spend more time on creative and high-level tasks.”

This shift has been augmented by training SilencerCo’s employees to monitor the robots doing the tedious jobs they used to do themselves. The employees gain new skills and quality control gets a boost because of the constant human monitoring of the new machines. The company has invested so heavily that the production floor is being rearranged to accommodate the new processes. But not one employee has lost their job because of it, and Shults says that none will. Better, more precise machines, coupled with better-skilled employees whose jobs are less tedious means superior products and happier customers.

Time 

Shults likes to say that “Time is time. Time is not money.” Time is the one resource we all have that cannot be replaced or made up. Once it’s gone, it’s gone for good. “You cannot put a price tag on time,” Shults said when asked about the subject. “It has so much more value than any amount someone can pay you. These new automations will give that valuable time back to our employees and our company, freeing up space to focus on growth and innovation.”

SilencerCo is leveraging that regained time to understand not only how to make better products, but how the machines that make them can be improved. Shults told us that all the best machine tools are currently made in Japan, and that SilencerCo only buys from those companies. But thanks to Shults’ emphasis on giving his employees their time back, the company has begun designing and building its own machines as well. Shults told us that designing those machines provides insights into how they can be improved and tailored to SilencerCo’s products, resulting in even better output as the SilencerCo team learns and improves. Some of those in-house machines are already online on the production floor.

Dogs Are Welcome!

This was our second visit to SilencerCo, and both times we noticed the dogs. Dogs in the offices. Dogs in the hallways. Dogs on the production floor. How many companies not only allow you bring your dog to work, but actively encourage it? We’d bet that SilencerCo is one of a very few.

We met this good boy in SilencerCo’s hallway. His name is Blue.” (Author’s Photo)

Obviously, not everyone is a dog person, but for those of us who are, that sounds like a great deal. And it goes back to employee well-being. Shults told us that “We love having a dog-friendly environment. It lowers stress levels and creates a fun space where people want to come to work. Our dogs are really part of our team!” He was excited about it. We get it. We were excited about it. The company even has a “Dog Station” with supplies folks might need for their canine pals. Good stuff.

Passion

We quickly noticed that the Three Ps, People, Passion, and Precision, overlap in many places. People who like their jobs find it easier to be passionate about what they do. That passion translates into quality work, quality products, and quality service.

But SilencerCo isn’t just passionate about suppressors and their accessories. A giant American flag hangs conspicuously over the production floor. Monthly “All Hands” meetings are held directly underneath that flag. Each meeting starts with the Pledge of Allegiance.

And it’s not just lip service. Shults and SilencerCo take that attitude seriously. “We source almost all of our materials within the United States and are working toward having everything 100 percent sourced in America,” he told us proudly. “We want our business to support Americans on all levels: through the products that we sell and through the methods [by which] these products are made.” He added that SilencerCo is currently the only suppressor company to do so.

The machinery and robotics investments also reflect the company’s ideals. SilencerCo has long been the only suppressor company to manufacture all their products in-house, from start to finish. Shults showed us the bar stock and other components that go into SilencerCo products. When asked why this vertical integration was important, Shults told us that “By manufacturing our products in-house, we are actively bringing more jobs to the people of Utah. It also gives us the ability to control our products and thereby ensures that customers are receiving the very best that we can produce.” Which brings us to…

Precision 

It’s not hard to see how SilencerCo’s focus on People and Passion leads to the final “P,” Precision. The company’s people continue to perform at higher levels, generating more passion and pride in what they do. The dogs no doubt play a vital role here too, because dogs just make everything better.

SilencerCo has long been regarded as a leader in the suppressor industry, with products like the Saker, Omega, Chimera, and Harvester series, among others. They are continuing that legacy with the new Velos Low Back Pressure suppressor designed specifically for the 5.56 NATO/.223 Remington cartridges.

The Velos LPB takes advantage of SilencerCo’s technology and people investments to make the most durable suppressor the company has ever made, thanks, in part, to the brand new patented Hoplon Blast Baffle. The Hoplon Baffle deflects debris and increases the suppressor’s lifespan on short-barreled rifles and full-auto firearms. It handles a standard-length semi-auto rifle with ease. The Velos LBP measures only 5.98 inches long and weighs 15.2 ounces.

Another innovation is the 3D-printed Inconel 635 core which is fully welded to the 17-4 stainless steel front and rear modules. The Velos LBP delivers an impressive 137.1 decibels at the muzzle of a 16-inch barreled AR-15. Just for reference, 140 decibels is considered hearing safe.

The Velos LBP features V-Series Cerakote to ensure the finish holds up to hard use. The new suppressor is compatible with the already popular SilencerCo Charlie accessories and has no barrel length restrictions. It ships with the brand-new Internal Charlie Flash Hider Front Cap, Charlie ASR Mount, ASR Flash Hider in ½ x 28, a spanner wrench, and a Charlie tool. Coupled with SilencerCo’s Gas Defeating Charging Handle, the Velos LBP may be the top AR-15 suppressor available today.

Precision Service

As always, SilencerCo backs up its products with perhaps the industry’s best warranty. Shults laughingly told us that he believes so strongly in supporting SilencerCo’s products that they’ve gone so far as to say “We’ll fix stupid once.”

When we pressed him on this he said “Being a consumer myself, I’ve experienced frustrations after purchasing a product and the manufacturer failing to provide support. That’s why providing top notch customer service and support is so important to me and why we focus so heavily on customer service and warranty…Our warranty department is in-house, and we maintain an average 48-hour turnaround time on suppressor warranty or service requests.”

So, the Three Ps come full circle back to People, with those People being SilencerCo’s customers. We admit that Shults’ confidence is contagious. It’s difficult to visit with him at SilencerCo and not feel that positive energy.

A Bright Future

SilencerCo’s investments in new machine tools, robotics, and processes are ultimately investments in their people, as we’ve noted. Such efforts rarely go unrewarded, and SilencerCo’s path forward appears surer than ever.

So, the Three Ps come full circle back to People, with those People being SilencerCo’s customers. We admit that Shults’ confidence is contagious. It’s difficult to visit with him at SilencerCo and not feel that positive energy.

A Bright Future

SilencerCo’s investments in new machine tools, robotics, and processes are ultimately investments in their people, as we’ve noted. Such efforts rarely go unrewarded, and SilencerCo’s path forward appears surer than ever.

Firearms technology is ever-evolving. Companies who ignore the adage “innovate or die,” rarely remain relevant, if they survive at all. Suppressor companies, as a subset of the firearms industry, face the same challenge. As suppressors grow more popular, companies must stay on or near the leading edge to compete. On a recent visit to SilencerCo, we saw what that company is doing not only to stay on the edge, but to drive it forward.

We spent time with SilencerCo Founder and CEO Jonathan Shults, Public Relations Specialist Shauna Young, and Marketing guys Caleb Gosnell and Cody Wootton. Along the way, we saw how SilencerCo is revamping its production facility and processes, looked at some new products, and did some live fire on the company’s indoor test range.

Changing For the Better

We were a bit surprised when Shults himself conducted the facility tour, but who better to brief us on everything that’s happening? Being an engineer, the focus quickly turned to SilencerCo’s investments in automation. Tedious jobs like sorting are being phased out. Robots now do that. But before you decry the employee losing his job, that’s not how it works. Not at SilencerCo, anyway.

The robots do replace the human doing mundane jobs, but that human is now trained to oversee the robot, making certain it’s performing as intended. Shults told us that “By introducing higher levels of automation…we are creating greater efficiency for our company and more enjoyable jobs for our employees.” Shults wants the automation to allow his people “to spend more time on creative and high-level tasks.”

Shults also noted that “Time is time. Time is not money.” When we asked what he meant by that, he responded that “You cannot put a price tag on time. It has so much more value than any amount someone can pay you. These new automations will give that valuable time back to our employees and our company, freeing up the space to focus on growth and innovation.”

Shults stressed that no one has lost their job to a machine, nor will they. We expect that such investments, coupled with the right motivation, greatly benefit employee morale. And we know that happy employees do superior work. Sounds like a winning formula.

New and Better Products

The new robots and machine tools have given the company the time and incentive to examine how and why top-quality machines perform well. Company engineers have begun building their own machine tools tailored for their products. In the process, they gain insights into how future products can and should be designed to maximize the machines’ capabilities, opening up new innovative avenues.

One of those new products is the Velos Low Back Pressure suppressor designed specifically for the 5.56 NATO and .223 Remington cartridges. Shults told us the Velos LBP is the most durable suppressor SilencerCo has ever built. When we pressed him on that claim, he enthusiastically told us about the new patented Hoplon Blast Baffle, which deflects debris and is specially designed to extend the suppressor’s life, even on short-barreled rifles and with fully automatic fire.

But that’s not the Velos’ only innovation. The 3D printed Inconel 625 core is fully welded to the 17-4 stainless steel front and rear modules using a unique manufacturing process that we aren’t qualified to describe. Suffice it to say that’s pretty awesome, as we found out when we shot it later that day. Plus, the V-Series Cerakote means the finish will hold up for a long time. But let’s take a look at the specs:

SilencerCo Velos Low Back Pressure Suppressor

– Length: 5.98 inches
– Weight: 15.2 ounces
– Decibels at the Muzzle: 137.1 dB
– Caliber: 5.56 NATO/.223 Remington
– Full Auto Rated
– No Barrel Length Restrictions
– 17-4 Stainless Steel with a 3D Printed Inconel Core
– Finish: V-Series Cerakote (Black)
– Compatible with SilencerCo Charlie Accessories

The Velos LBP suppressor ships with the brand-new Charlie Flash Hider Front Cap, Charlie ASR Mount, ASR Flash Hider in ½ x 28, spanner wrench, and Charlie Tool.

We were able to try out the Velos LBP on several platforms at the indoor range. It was a real pleasure to shoot. Being indoors, we used ear pro, but it was still noticeably quiet. It almost seems wimpy to say it tamed the recoil a bit, being 5.56, but it did. And the gas was reduced too, as one would expect from the name. When we coupled it with the SilencerCo Gas Defeating Charging Handle, there seemed to be no gas at all.

The Velos was fun all around but, unsurprisingly, we enjoyed the FightLite Industries Dual Feed AR the most. Seriously, what’s not to like about that combo? That the range time was the highlight of the day should not shock anyone either. It was a good time. If you’re looking for a dedicated suppressor for your AR-15, you might want to give the Velos LBP a hard look.

The Dogs

We would be remiss if we didn’t mention the good boys and girls that we saw around the SilencerCo facility. Seriously. The company encourages their employees to bring their dogs to work. Talk about a morale booster. They weren’t on the range, for obvious reasons, but we saw them in the offices, hallways, and even the production floor, which isn’t particularly loud. It just made everything better. Shults said, enthusiastically, that “Our dogs are really part of our team!”

This good boy’s name is Blue. We met him in a SilencerCo hallway on the way to the production floor. (Author’s Photo)

Doing Everything at Home

By “at home,” we mean that SilencerCo sources almost all their materials from the United States and is “working toward having everything 100 percent sourced in America,” according to Shults. “We want our business to support Americans on all levels: through the products that we sell and through the methods these products are made.”

The company is also as vertically integrated as it can be, doing all the manufacturing work in-house, the only suppressor company to do so. Shults told us that was important to him because it brings jobs to the people of Utah while giving the company “the ability to control our products and thereby ensures that customers are receiving the very best that we can produce.”

Those attitudes aren’t just lip service. Both times we’ve visited SilencerCo we’ve noticed the huge American flag hanging prominently above the production floor. Monthly “all hands” meetings are held under the flags, with each meeting opening with the Pledge of Allegiance.” Good stuff.

Quality Service

Shults also emphasized the importance of customer service. After all, a company that doesn’t support its products and its customers won’t stay around long. The SilencerCo warranty department is also in-house, and Shults says they usually turn warranty work around in 48 hours. He takes his company’s warranty so seriously that he laughingly told us that SilencerCo would even “fix stupid once.” We liked that.

Of course, in a perfect world, warranties would be unnecessary, and we’ve heard folks disparage companies who offer them by saying they shouldn’t have to do so. But that’s just unrealistic, and such bombastic comments aren’t helpful. The fact that good companies support their products is encouraging.

Looking Ahead

Shults’ enthusiasm for SilencerCo’s direction is contagious. But it wasn’t just him. The other folks we interacted with had the same energy. The employees on the production floor were focused and quite friendly when we asked them questions. Now, you could say that was because the boss was right there with us, but we should note that the boss was on an easy first-name basis with everyone too. That’s a good sign.

That SilencerCo’s efforts to improve the experience and skills of their workers is a good thing seems unarguable. Happy employees take pride in their work, and everyone benefits, including the end user of SilencerCo products.

A firearms instructor once told us to buy and use products from companies “who give a damn about their customers.” It looks like Shults is fostering that kind of environment at SilencerCo. The company started fifteen years ago in a garage. Now it’s an industry leader. They must be doing something right.

The 300 Blackout is a versatile and favored cartridge for hunting, home defense, and suppressed shooting. But if you want to ensure the best possible performance, you’ll need to select the right barrel length. This guide outlines the advantages and disadvantages of different barrel lengths for the 300 Blackout and where to purchase them.

The main question you need to ask yourself is whether or not you plan on using a suppressor. If you’re looking for the quietest and best handling setup, one could easily go as short as 7.5″, offered which is offered by Faxon Firearms.

How Much Does Barrel Length Affect .300 Blackout Velocity?

Based on our personal experience and research, the 9″ 300 blackout barrel is the best overall barrel length with or without a suppressor, especially since an 8″ barrel is the minimum warranty barrel length for many suppressor manufacturers.

Best Barrel Length For Suppressed 300 Blackout

For optimal performance with a suppressed 300 Blackout; we recommend a barrel length of 8″-10″.

Attaching a 6″ suppressor to this barrel length results in a total length of 14″ to 16″, which provides optimal muzzle velocity for accurate long-range shots.

For the longer range engagements with a suppressed 300 Blackout, use a 16″ barrel with a suppressor for an average velocity of over 2,630 fps, leading to more effective shots and minimal bullet drop.

Best 300 Blackout Barrel Length For Home Defense

The .300 Blackout round is an excellent choice for home defense as it combines power and efficiency with lethality when fired from a short-barreled rifle.

Using a short-barreled rifle is ideal for home defense as its compactness makes it easier to maneuver throughout the home. Despite its compact size, a .300 BLK round fired from a short barrel can still hit targets up to 100 yards away.

For optimal home defense with the .300 Blackout, a barrel length of at least 6″ to 8″ is recommended.

Using a short-barreled rifle is ideal for home defense as its compactness makes it easier to maneuver throughout the home. Despite its compact size, a .300 BLK round fired from a short barrel can still hit targets up to 100 yards away.

For optimal home defense with the .300 Blackout, a barrel length of at least 6″ to 8″ is recommended.

Best 300 Blackout Barrel Length For Hunting

The ideal barrel length when hunting with .300 Blackout is one able to reach long-range targets with sufficient bullet velocity and energy on target for a lethal impact.

Longer barrel lengths offer greater accuracy and velocity, with a maximum length of 16″ for the .300 Blackout. This length ensures complete gunpowder combustion to generate maximum force and stabilizes the bullet for a flatter trajectory and improved accuracy.

Additionally, a 16″ barrel offers a long line of sight for better aim, making it the recommended choice for long-range hunting.

Choosing the right barrel length for the .300 BLK can be hard

At 10″, the muzzle velocity has not yet reached its peak. Heavy subsonic ammo in a 10″ barrel may have lower velocities but allows for the use of a suppressor without damaging your hearing. Supersonic ammo out of a 10″ barrel retains rifle caliber velocities but with more significant bullet drop at longer distances.

At 16″, muzzle velocities are near their maximum. As a result, heavy-grain subsonic bullets struggle to retain their subsonic terminal performance, while supersonic ammo has increased effective range and reduced bullet drop. The 16″ barrel also provides greater energy upon impact, regardless of ammo type.

The barrel twist rate also impacts performance and should be considered when selecting barrel length and determining the effective range of the .300 Blackout. For example, a 1:8 twist is best for lightweight supersonic rounds, while the 1:7 twist is recommended for heavy subsonic rounds with a suppressor.

There are a few factors to consider when selecting the ideal barrel length for the .300 BLK rifle and determining its effective range.
