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 will do just that… keep watch… overwatch, that is. That’s what Faxon Firearms advises. 

Here’s more of that they say: 

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 Blackout. The standard 5.56 NATO cartridge loses a lot of velocity and power at a distance. So, 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 Blackout, 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 Blackout MuzzLok Muzzle Device, and the impressive 1:3 twist Big Gunner Profile Barrel. Faxon’s Lifetime Guarantee also backs the Faxon Sentinel.
