LEO® Telescoping Stock Adapter For Moss 500/590A1/Mav88 (12-GA And 20-GA)
Use Mesa Tactical’s collapsible stock kits and adapters to install AR-15 adjustable buttstocks and pistol grips onto the venerable Mossberg 500, Remington 870 and Beretta 1301 shotgun platforms for the ultimate in tactical shotgun configuration performance.
The LEO aluminum adapter kits include everything necessary to retrofit Remington or Mossberg pump shotguns with most AR-15 style stocks and pistol grips. Our adapter kits allow customers to add their own AR-15 stock assemblies as desired. LEO® telescoping stock adapters, feature a stock elevation about an inch lower than the High-tube adapters and so don’t require sighting or aiming aids.
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 shotgun’s 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.
Our LEO stock adapters are investment cast aircraft aluminum. They are then CNC machined and anodized with a Type III Class 2 Mil-spec finish. To meet the requirements of professional operators as well as competitors, we offer two lines of telescoping stock systems: High-tube® and LEO.
The LEO adapter is our most basic, best-selling model, and features an optimal stock elevation allowing the use of iron sights or even the bead sight. All LEO adapters accept optional push-button sling swivels, and Remington 870 LEO adapters can accept stamped steel sling loop and hook loops.
These adapters are available in two types of kits, adapter kits or complete stock kits.
