H2 Buffer

H2 Buffer
4.6 oz
The H2 buffer adds needed weight to the reciprocating mass to ensure reliable performance with the 300BLK SBR, as well as 5.56NATO rifles. 

 The H2 buffer is a heavier buffer that replaces your standard buffer for reliable performance out of your 9 or 12.5 300BLK. The standard buffer in an AR-15 Carbine is 2.9oz and intended for use with a mid/rifle length gas system. When you move to a carbine length gas system an H-buffer weighing 3.8oz is used. Because the gas system in the 300BLK 9 and 12.5 is a pistol length gas system, a heavier buffer is used for better performance.
