CMC Triggers Carbine Buffer Features The CMC Triggers Carbine Buffer weighs 3 ounces a weight commonly used in carbine length AR-15 buffer tube and spring combinations to achieve reliable cycling with a wide range of ammunition. Properly matching buffer weight to the rifle s gas system and ammunition helps reduce bolt bounce and felt recoil improving both reliability and shooter comfort. This buffer is built to fit standard AR-15 carbine buffer tubes making it a straightforward swap for shooters looking to fine tune their rifle s function. Its black finish matches standard AR-15 hardware for a clean factory appearance. Installing a correctly weighted buffer can smooth out an AR-15 s cycle particularly on rifles running a pistol length or carbine length gas system where timing is more sensitive to buffer weight. Builders assembling a complete lower receiver will need a buffer like this one to complete the buffer tube assembly alongside a compatible spring. This CMC Triggers buffer offers a simple inexpensive way to address cycling issues or simply complete a new build. AR-15 owners looking to dial in reliability without major modifications will find this buffer a practical addition to their parts bin.
