Flexible Function for Your PCC Setup
The KynSHOT RB5015HD Recoil Buffer is a hydraulic buffer system designed and optimized to fit PCC’s using a Mil-Spec style carbine
buffer tube (internal depth 7″). The RB5015HD can be paired with any style buffer spring, and is a simple drop-in replacement for all buffer
systems on the market.
The RB5015HD works in PCC builds using barrel lengths 8″ and up, or all suppressed PCC’s. The RB5015HD also works with all 9mm
loads, and its weight and length have been optimized for the PCC applications so that it runs reliably, softens recoil, and stops just behind
the bolt catch. Our buffers patented technology absorbs the recoil impulse from the bolt carrier’s rearward motion, preventing bolt bounce
as a new round is chambered.
The RB5015HD reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip. Our test data shows that
the time to reacquire a target decreases, and in most cases the shooter will not have to leave their scope after taking their shot.
The R5015HD can be used with an A5/AR-10 buffer tube (internal depth 7.75″), if you are using the A5 buffer tube configuration, the
RB015HD should be paired with P/N: R1505098 (KynSHOT Spacer Weight). If you are shooting a CMMG Radial Delayed Blowback
system, the buffer does not need to be paired with a spacer weight.
Please Note: We recommend keeping the weight in your bolt. Removing the weight to get a lighter bolt is not recommended in
blowback PCC’s, even if using light competition loads.
