The Kynshot hydraulic recoil buffer is made specifically for the H&K MR762 (Kynshot part no. RB5030). Kynshot adds weight and a refined hydraulic design to smooth out cycling compared with other MR762 buffer options, and it works with the factory MR762 spring. It is a drop-in replacement for the standard buffer system, so there is nothing to modify. Using patented technology, it absorbs recoil energy as the bolt carrier moves rearward and helps reduce bolt bounce during chambering.

Key Specifications

• It is engineered for the H&K MR762 and is compatible only with that rifle.
• Felt recoil drops by 30 percent or more, which improves control and reduces muzzle rise.
• The weight is 8.3 ounces, heavier than a standard buffer to smooth cycling.
• The overall length is 3.92 inches, sized for the MR762 buffer tube.
• The buffer diameter is 0.965 inches, matching the MR762 buffer system.
• Construction is 17-4 stainless steel throughout, which resists corrosion and wear.
• It uses mil-spec hydraulic fluids and seals for consistent damping.
• The unit is certified for ambient temperatures from -30 to +150 degrees F, so it works in cold and heat.
• It reduces bolt speed and bolt bounce, which speeds shot recovery and lowers wear on the rifle.
• The buffer is 100 percent made in the USA, and it installs as a drop-in with the factory spring.
