Kynshot Rb5007 Recoil Buffer S/S$159.95
Availability: In Stock
The Kynshot RB5020SS short stroke recoil buffer is a hydraulic damping system built for PCC (pistol caliber carbine) shooters who need faster sight recovery and quicker follow-up shots on the clock. Developed in cooperation with Blitzkrieg Components, this stainless steel buffer delivers a measurable reduction in felt recoil while shortening the bolt stroke—key advantages in competition where every millisecond counts. Drop it into your existing buffer tube setup and get back on target faster without swapping your entire system.
The 5.3" compressed length keeps things compact while dramatically changing how your PCC cycles. Install it in a standard AR-15 carbine tube and you'll shorten bolt stroke by 1.3"; go with an AR-10/A5 tube and you'll see a 0.5" reduction (extendable via spacers if you want to fine-tune further). The hydraulic damping is tuned specifically for lighter, competition-grade 9mm loadings, so it performs best—and lasts longest—when you're running the kind of ammo you'll actually use at the range or match.
Kynshot engineered this buffer to handle the demands of short-stroke PCC builds without requiring you to redesign your lower or swap springs. It's a straightforward way to soften recoil impulse and improve reliability across the cycling window, especially if you're running a tight, optimized competition tune.
