The Kynshot Buffer Ovr Gsd AR15/CMMG PCC is a hydraulic recoil management system engineered for shooters who demand precision and control in intermediate-caliber platforms. Designed specifically for AR-15 and CMMG Pistol Caliber Carbines, this buffer addresses the unique recoil signature of PCC systems, which operate at higher velocities than traditional handgun cartridges but in a shorter bolt travel envelope. Law enforcement and competitive shooters choose this buffer when follow-up accuracy and reduced muzzle rise are mission-critical.
Kynshot's proprietary hydraulic-over-spring design uses precision-tuned dampening to absorb and dissipate recoil energy more effectively than solid or standard spring buffers. The system maintains consistent performance across environmental temperature ranges and does not degrade with extended use, unlike rubber or elastomer-based alternatives. At 0.38 lbs, the buffer integrates seamlessly into your receiver extension with no modifications required, and the oversized geometry is engineered to work harmoniously with heavier bolt carrier groups and suppressed fire without accelerated wear.
This buffer is ideal for operators running CMMG 9mm or .45 ACP PCC uppers who need to tighten groups and control muzzle movement during rapid-fire sequences. Installation requires no gunsmithing—simply swap it into any standard AR-15 tube compatible with your platform. Whether you're training for duty qualification, running match stages, or building a dedicated PCC for home defense, the Kynshot Buffer Ovr Gsd delivers the recoil management that separates consistent hits from spray-and-pray performance. Verify tube compatibility with your specific receiver before ordering.
