This Kynshot hydraulic recoil buffer (brand part number RB5006) is built for any AR-10 running a mil-spec-style, rifle-length A1 or A2 fixed buffer tube with a 9.5-inch internal depth. It works with any standard rifle buffer spring and installs as a simple drop-in replacement for whatever buffer system is currently in the gun. Kynshot’s patented hydraulic technology absorbs the recoil impulse generated by the bolt carrier’s rearward motion, preventing bolt bounce as the next round chambers and cutting felt recoil by roughly 30 percent, which helps the shooter stay on target for faster, more accurate follow-up shots.
