Angstadt Arms Hydraulic Buffer Kit – 9mm/40 S&W/45 ACP Heavy

The Angstadt Arms Hydraulic Buffer Kit for pistol-caliber carbines delivers smoother cycling and reduced felt recoil in blowback-operated firearms. Designed specifically for 9mm, 40 S&W, and 45 ACP platforms, this heavy-weight buffer uses hydraulic dampening technology to control bolt speed and minimize carrier bounce, resulting in faster follow-up shots and improved reliability with a wide range of ammunition loads.

Constructed with precision-machined components and hydraulic fluid sealed in a durable housing, this buffer kit is engineered for high round counts without performance degradation. Direct drop-in installation requires no gunsmithing—simply remove your existing buffer and spring, then install this kit in your standard carbine buffer tube. The heavy weight configuration is optimized for suppressed shooting and full-power defensive loads.
