The Bear Creek Arsenal AR-15 is a semi-automatic rifle chambered in .300 Blackout with a 16" barrel, 30+1 capacity, 7075 forged aluminum flat-top upper, 15" M-LOK free-float handguard, and BCA mil-spec lower with 6-position stock and 30-round polymer window magazine. The Bear Creek Arsenal AR-15 is built around a 16" barrel chambered in .300 Blackout with a 1:8" twist rate, 5/8"x24 threaded muzzle finished with a BCA spiral flash hider, low-profile gas block, and a BCA bolt carrier group featuring an E9310 steel bolt for superior toughness and durability through sustained hard use. The 7075 forged aluminum flat-top M4 upper receiver is machined to mil-spec standards and pairs with the BCA mil-spec engraved lower for a complete, matched upper and lower assembly. The 5/8"x24 thread pattern provides immediate suppressor compatibility for shooters who want to run the .300 Blackout suppressed. The BCA .300 Blackout complete AR-15 rifle features the Talon 15" M-LOK free-float split rail handguard that provides extensive accessory mounting real estate for lights, lasers, grips, and other tactical accessories while free-floating the barrel for improved accuracy potential. The 6-position retractable mil-spec stock allows length of pull adjustment for a wide range of shooters and shooting positions, and the A2 pistol grip with American flag adds a patriotic aesthetic to an already capable and complete AR-15 package. A 30-round polymer window magazine is included for immediate range readiness.
