Mesa 92170 Enidine Shot Stock Hydraulic Buffer
Any Mesa Tactical telescoping stock kit can be upgraded with an Enidine hydraulic recoil buffer to reduce felt recoil by up to 70%.
These hydraulic recoil buffer assemblies replace the receiver extension tubes in our stock kits. They are of mil-spec diameter, giving them a snug fit with mil-spec buttstocks; and a looser, though still tolerable fit with "commercial" aftermarket buttstocks. CANNOT BE FITTED TO AR-15 RIFLES.
