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.

• Drop-in Replacement for Any Buffer System.
• Reduces Felt Recoil by 30%.
• Improves Firearm Reliability.
• Designed for 9mm PCC's using 3.5"-7.5" Barrel Length.
• The RB5007 can also be used with an A5 Buffer Tube on your AR-15 (.223/5.56), and will Replace the Standard A5 Buffer System.
