CMMG AR15 H3 Buffer Assembly Features The CMMG AR15 H3 Buffer Assembly adds extra mass to the buffer system which slows bolt carrier velocity during the recoil cycle. This added weight helps tame felt recoil giving the shooter a smoother more controllable experience during rapid strings of fire. A heavier buffer like the H3 can also correct erratic case ejection patterns that sometimes occur with lighter buffers in certain builds. At 5.4 ounces the H3 sits at the top end of CMMG s buffer weight options making it the go-to choice once lighter buffers have been tried and found insufficient. CMMG recommends increasing buffer weight incrementally rather than jumping straight to the heaviest option since an overly heavy buffer can create its own function issues if the rest of the system is not tuned to match. This step by step approach lets a shooter dial in recoil management and ejection consistency without overcorrecting. Finished in silver the buffer assembly is built to CMMG s standards for durability and fit in AR-platform rifles. Every CMMG product including the H3 Buffer Assembly is backed by CMMG s Lifetime Quality Guarantee for long-term peace of mind.
