The 9mm Silent Captured Spring is a drop-in component that softens recoil and reduces cycling noise and vibration in your 9mm carbine. The result is a refined rifle that's a pleasure to shoot. Paired with our 9mm bolt assembly, you have the most reliable 9mm operating system available. The 9mm Enhanced Version provides the same buffering mass as our standard 9mm SCS. At the same time, we've increased overall bolt mass slightly with more room for increased weight if needed. The result is even softer recoil thanks to a further delay in blowback.

The hydraulic shock absorber (Buffer) is specially designed for all PCC rifles that operate on the principle of unlocked bolt. In combination with the right spring, it enables the elimination of unpleasant recoil that most PCC AR rifles are known to have.
