300 BLACKOUT


ALL UPPERS REQUIRE SIGNATURE CONFIRMATION

BUILD TIMES ARE 1 to 2 WEEKS ~ ADDING CERAKOTE ADDS AN ADDITIONAL 1 to 2 WEEKS 

Black Rifle Arms 300BLK gas systems are precisely tuned for reliability through a combination of gas port location and barrel length. Using the standard pistol length gas system with 8 and 10" barrels, and utilizing our 300BLK intermediate length gas system with 13.5" and 16” barrels enable us to locate the gas port in the optimal location to balance subsonic dwell time and supersonic pressure curve to offer ultra-reliability without adding to the complexity of a gas regulator. 

Why Do You Not Offer A Gas Regulated 300BLK Uppers?
