It’s all in the name…Sentinel. A Sentinel is a guard whose job it is to stand and keep watch. The Faxon Firearms Sentinel chambered in 8.6 Blackout will do just that…keep watch…overwatch that is. The AR-15, no doubt, is America’s favorite rifle. But even America’s rifle has its limitations. The primary limitation is that it cannot handle long-action cartridges such as the 8.6 BLK. The standard 5.56 NATO cartridge loses a lot of velocity and power at distance. To get over that hurdle, but still have the same feel of an AR-15, you’re looking at an AR10.

The AR10 has the same look and feel as the AR-15. But you can now shoot longer action cartridges such as the 8.6 BLK, 308 WIN, and 6.5 Creedmoor.

The Sentinel 8.6 BLK, part of Faxon’s Summit Line of firearms, boasts a billet aluminum receiver set, G3 Aluminum Streamline M-LOK Handguard, new 8.6 BLK MuzzLok Muzzle Device, and the impressive 1:3 twist Big Gunner Profile Barrel. The Faxon Sentinel is also backed by Faxon’s Lifetime Guarantee.
