LEO® Gen II Telescoping Stock Adapter for Rem 870 (12-GA only)

Mesa Tactical's LEO® Gen II Telescoping Stock adapter and pistol grip system for the Remington 870 shotgun is made specifically with law enforcement in mind. The LEO Stock adapter system is designed to allow shooters the ability to fit AR style collapsible stocks and pistol grips onto their shotguns, while allowing use of open or bead sights. The versatile telescoping stock adapter system can be fitted with a standard AR-15 grip and telescoping stock, which enables tactical operators to instantly adjust the length of pull of the telescoping stock in order to accommodate differences in individual body sizes or use of body armor. 

The LEO adapter is available in three types of kits, adapter kits, recoil starter packs or complete stock kits. Mesa Tactical’s upgraded versions include KynSHOT's hydraulic recoil buffers which replace the standard receiver extension tube normally used with AR-15 style telescoping stock assemblies. The recoil buffer is manufactured for Mesa Tactical by Kyntec. The KynSHOT hydraulic buffers (Mil-spec) are a recoil reducer designed for professional operators who require optimum accuracy and control. The KynSHOT hydraulic recoil buffers reduce felt recoil from 70% up to 90%.

    Well thought out design

    The adapter and recoil tube are both well thought out and fit snugly to my Remington 870. Printed documentation could use a refresh, but they answered my questions by phone immediately. Install was a breeze.
