CMMG AR-15 Buffer Assembly H2 Features The CMMG AR-15 Buffer Assembly H2 combines one steel weight with two tungsten weights inside a steel buffer body giving it more mass than a standard H buffer at a total weight of 4.6 oz. That extra mass slows the bolt carrier group s rearward travel slightly which helps tame felt recoil and softens the overall impulse of the rifle. A heavier buffer can also correct erratic case ejection since it changes the timing of the cycle relative to gas pressure and bolt velocity. This makes the H2 buffer a common step up for shooters running suppressors adjustable gas blocks or simply looking for a softer-shooting AR-15. CMMG recommends increasing buffer weight incrementally when tuning a rifle s cycle rather than jumping straight to the heaviest option available since too heavy a buffer can cause short-stroking or failure to lock back. The H2 sits as a middle step in that process making it a practical choice for shooters methodically dialing in their rifle s function. Every CMMG buffer assembly is backed by the company s Lifetime Quality Guarantee giving buyers confidence in the part s long-term reliability. For AR-15 owners working through a tuning process or simply looking to reduce recoil the CMMG AR-15 Buffer Assembly H2 is available for sale at GrabAGun.
