KynSHOT RB5007 Hydraulic Recoil Buffer, Fits AR-9 Style PCC's Using a Mil-Spec Style Carbine Buffer Tube (Internal Depth 7) and a Barrel Length of 3.5-7.5, Stainless Steel Construction, Silver RB5007

The KynSHOT RB5007 Recoil Buffer is a hydraulic buffer system designed and optimized to fit 9mm PCC's using a Mil-Spec style carbine buffer tube (internal depth 7"). The RB5007 can be paired with any style buffer spring, and is a simple drop-in replacement for all buffer systems on the market. The RB5007 can be used with an A5/AR-10 buffer tube (internal depth 7.75"). If you are shooting a CMMG Radial Delayed Blowback system, the buffer does not need to be paired with a spacer weight.
