300 Blackout Barrels

Browse the high performance 300 Blackout Barrels from Bear Creek Arsenal and experience precision and reliability for your 300 Blackout Rifle or Pistol. The 300 Blackout, popularized for its ability to fire both subsonic and supersonic ammunition with a suppressor, are available in a variety of lengths, flutes, and finishes. Expertly crafted from premium 416R Stainless Steel and 4150 Chrome Moly Vanadium steel, they offer great accuracy and durability. Upgrading to the 300 Blackout is made easier, as it is uses the same 5.56 NATO parts like the BCG, allowing you the choice to swap the barrel with your current upper or instead purchase a complete 300 Blackout Upper to attach to a MILSPEC AR-15 lower out of the box!
