Mesa Tactical LEO adapter by Scott, Verified Owner, July 21, 2023
Fits the Mossberg 500 20g bantam beautifully and the quality is top notch. Comes with QD insert and all mounting hardware. Utilizes mil-spec tubes and castle nuts. The grip angle mounting position is steep, so a 17.5 degree grip ends up nearly, but n...

Product Info for Mesa Tactical LEO Gen II Tele Collapsible Shotgun Stock Adapter

Use Mesa Tacticals collapsible stock adapters to install AR-15 adjustable buttstocks and pistol grips onto the venerable Mossberg 500 shotgun platforms for the ultimate in tactical shotgun configuration performance. The LEO adapter is the most basic, best-selling model, and features an optimal stock elevation allowing the use of iron sights or even the bead sight.image

The concept behind the telescoping stock system is simple: the shotgun stock is replaced by an adapter, which attaches to the rear end of the shotguns receiver and it, in turn, mimics the rear end of an AR-15 lower receiver, into which an AR-15 receiver extension tube can be threaded. The AR-15 telescoping stock and pistol grip can then be reliably attached.
