Questions & Answers
So this is the one to use with the vltor buffer tube, not the rb5007 then? AI Answer

Yes, this RB5000A5 buffer is the correct one for a Vltor A5 buffer tube since it is built specifically for the 7.75in A5 depth and drops in without extra parts, whereas the RB5007 is meant for a 7in carbine tube and needs an added spacer weight to work in an A5 tube.

Product Info for KynSHOT AR-15 Recoil Buffer

KynSHOT encourages everyone to follow the proper gun safety guidelines when handling any firearm at all times.image

The KynSHOT RB5000A5 is a hydraulic recoil buffer specifically engineered for lightly cycling, tuned, and under-gassed AR-15 platforms using a Mil-Spec A5 buffer tube with a 7.75in internal depth. Its optimized spring rate and inherent hydraulic damping characteristics allow shooters to fine-tune low-gas systems while maintaining reliable cycling performance.

Designed as a direct drop-in replacement for any A5 buffer system, the RB5000A5 is compatible with all standard A5 buffer springs. It is also uniquely suited for pistol-caliber carbines utilizing delayed-blowback operating systems, including radial-delayed, roller-delayed, bearing-delayed, and chamber-ring-delayed designs, making integration simple across a wide variety of firearm configurations.

Built around our patented hydraulic recoil-reduction technology, the RB5000A5 can reduce felt recoil by up to 30%. Internal testing has demonstrated faster target reacquisition, and less gas to reverted back to the shooter when shooting suppressed, helping shooters stay on target and transition more efficiently between shots.
