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.

FAQ - Team 4GT

Q: What are the recommended grips for this stock adapter?

A: Any flat top grip (grips without beaver tail) should work well. Popular grips used are the ERGO® Flat Top Tactical Deluxe Grip and Hogue® AR-15/M-16 OverMolded Rubber Grip with Finger Grooves.

Other suitable grips are the ERGO® A2 STO Grip, ERGO® Swift Grip, and Hogue® AR-15/M-16 OverMolded Rubber Grip w/ Cargo Management System Storage Kit

Q: Does the ERGO® F93 Pro Stock 5.56 work with this stock adapter? How about the ERGO® F93 Pro Stock .308?

A: Yes, both work very well. The ERGO® F93 Pro 5.56 and .308 stocks have identical external dimensions. The internal spring space in the 5.56 stock is designed to accommodate an AR-15 spring and the .308 stock is designed to accommodate an AR-10 spring. When mounted on shotguns this internal spring space is not used.

Q: What is the hole in the side of the adapter for?

A: This is a standard push-button sling swivel attachment point. Suitable accessories for this mounting point include the Mesa Tactical™ Heavy Duty Quick Detach Swivel and the Viking Tactics™ Heavy Duty Quick Detach Swivel.
