Another Grendel comes to life!

[Variable]

A standard rifle buffer is 5.2 oz., so there aren't many carbine buffers that can come close to that weight. Another thing about AR15 buffers for high-power rifle cartidges is that the reciprocating internal weights are important to prevent bolt carrier bounce. Some people figure throwing in a 9mm SMG buffer will do the trick because they are so heavy, but the buffer body is heavier on a 9mm buffer since there is no gas system or locking mechanism on a 9mm SMG. The series of carbine heavy buffers for the 5.56 Commando-length barrel guns are there to compensate for the increased gas port diameter necessary to run a 10", 10.5", 11.5", and 14.5" barrels.
