This buffer is commonly found in builds utilizing the 5.56 NATO caliber, making it a suitable choice for builders looking to enhance performance in their carbine platform.

colt H2 carbine buffer, weight feels right on a 14.5 mid length. install was a bit fiddly because the buffer detent on my tube was a touch sticky, cleaned the detent slot with a pick and it dropped in smooth. ejection moved to a tight pile after install
