Product Description The Maxim Defense MXM47567 CQB Generation 2 Buffer and Spring H3 Assembly is a precision-engineered recoil management accessory designed for AR-15 platform rifles. Engineered for Close Quarters Battle (CQB) applications, this Generation 2 buffer and spring kit pairs an H3-weight buffer with a matched recoil spring to deliver reliable cycling, reduced felt recoil, and enhanced durability. The H3 designation indicates a heavier buffer weight, making it an ideal choice for shooters running pistol-caliber conversions, suppressed setups, or overgassed gas systems that benefit from added mass to slow the bolt carrier group. The polished stainless steel spring and precision-machined buffer work in concert to optimize function and extend the service life of your platform.
