KynSHOT RB5007 Hydraulic Recoil Buffer for 9mm AR9 PCC, 3.5–7.5 in Barrels

Product Description

The KynSHOT RB5007 Recoil Buffer is a hydraulic recoil buffer system engineered for 9mm pistol-caliber carbines (PCC) and AR9 builds using a Mil-Spec style carbine buffer tube (7" internal depth). Designed as a simple drop-in replacement, it helps soften recoil and improve cycling for smoother, more reliable performance. The RB5007 is optimized for 3.5"–7.5" barrel-length PCC builds and can also be used with an A5/AR-10 buffer tube (7.75" internal depth). When used with a CMMG Radial Delayed Blowback system, it does not require pairing with a spacer weight.
