From the manufacturer
Faxon and Brownells have again teamed up to bring a unique barrel to market with this line of AR-15 Suppressor Optimized Barrels chambered in 300 Blackout.
One of the unique design features in this line of barrels is the tapered muzzle shoulder which allows for direct mounting of suppressors from companies like Q LLC or Sig Sauer.
If you don’t yet have a suppressor that utilizes the tapered mounting or you simple want to mount a conventional muzzle devise don’t worry, we’ve got you covered. Each barrel comes with an adapter that gives you a standard ninety degree should angle.
The Suppressor Optimized Barrels have a medium taper profile, 5/8-24 threads, 1-7 rate of twist, and are made of 4150 steel with a nitride finish.
