Use Mesa Tactical’s collapsible stock adapters to install AR-15 adjustable buttstocks and pistol grips onto the venerable Remington 870 and Mossberg 500/590 shotgun platforms for the ultimate in tactical shotgun configuration performance. The concept is simple: the shotgun stock is replaced by an adapter that mimics the stock attachment point of an AR-15 lower receiver. This adapter accepts an AR-15 receiver buffer tube. The AR-15 collapsible stock and pistol grip can then be reliably attached to the shotgun. The stock adapters are investment cast aircraft grade aluminum, CNC machined and powdercoated black with a tough, chemical resistant finish.
The LEO adapter 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 pocket sling loop and hook loops.
