Overview
The KynSHOT RB5015HD is a 6.0-ounce hydraulic buffer built for the harder rearward impulse of simple-blowback 9mm PCCs. Its internal damping acts during the recoil stroke instead of relying on dead weight alone. KynSHOT positions this Heavy Damped model for barrels 8 inches or longer and for suppressed 9mm PCCs, where added bolt speed and impact can make a lighter buffer feel sharp.
The RB5015HD measures 4.35 inches overall, compresses to 3.90 inches, and has a 0.76-inch diameter. Its standard installation is a mil-spec carbine receiver extension with 7 inches of internal depth. The body uses 17-4 stainless steel throughout. KynSHOT also allows the buffer in an A5 or AR-10 receiver extension with 7.75 inches of internal depth when it is paired with KynSHOT's matching spacer weight.
This is not the catch-all KynSHOT choice for every delayed PCC. KynSHOT recommends the RB5000HP instead for a CMMG Radial Delayed Blowback carrier running in a carbine-length tube. Choose the RB5015HD when the build is a simple-blowback AR-9 in its stated barrel or suppressed use range, then match the receiver-extension depth before assembly.
Key Features
- Hydraulic damping tuned for pistol-caliber carbine recoil
- 6.0 oz weight for heavier simple-blowback 9mm setups
- 4.35 in overall length and 3.90 in compressed length
- 0.76 in diameter
- 17-4 stainless steel construction throughout
- Direct fit in a 7 in internal-depth carbine receiver extension
- A5 and AR-10 tube support with the KynSHOT spacer weight
Pros
- +Manufacturer-tuned for 8-inch-plus or suppressed 9mm PCCs
- +Hydraulic damping manages bolt impact without an adjustable weight stack
- +Six-ounce mass suits heavier simple-blowback operating cycles
- +Can move to an A5 or AR-10 tube when paired with the correct spacer weight
Cons
- −Costs more than a conventional solid or dead-blow PCC buffer
- −Needs the KynSHOT spacer weight in a 7.75-inch A5 or AR-10 tube
- −Not KynSHOT's recommended carbine-tube buffer for CMMG Radial Delayed Blowback
- −Heavy specification is not the preferred KynSHOT option for short unsuppressed barrels
