Maxim Defense JP Silent Captured Spring – Heavy Tungsten/Stainless Steel
Upgrade your rifle’s performance with the Maxim Defense JP Silent Captured Spring (SCS) – Heavy Tungsten/Stainless Steel system. Built for enhanced cycling, reduced recoil, and near-silent buffer operation, this drop-in upgrade is a game-changer for AR-15 and AR-style platforms seeking maximum performance and smoother shooting.
The Maxim Defense JP Silent Captured Spring Heavy (H2 equivalent) uses a high-mass tungsten/stainless steel configuration to significantly dampen recoil and minimize bolt bounce. By eliminating the traditional buffer spring noise and vibration, this system provides quieter, more reliable operation, especially for suppressed or short-barreled rifles (SBRs).
This SCS unit combines JP Enterprises’ proven buffer system with Maxim Defense’s compact, mission-ready design, making it ideal for duty weapons, competitive builds, or custom ARs.
