LEO® Gen II Telescoping Stock Kit 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 500/590 shotgun platforms for the ultimate in tactical shotgun configuration performance.
Equipped with the Mesa Tactical stock adapter, the shotguns have an adjustable length-of-pull to perfectly fit to the shooter’s stature or equipment, such as body armor; feature handling characteristics similar to the ubiquitous AR-15; are more compact for transport and storage; and are more controllable due to the pistol grip configuration.
LEO® telescoping stock adapters, which feature a stock elevation about an inch lower than our High-tube adapters and so don’t require sighting or aiming aids.
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.
Stock kits additionally include an M4 Carbine style telescoping buttstock assembly, an ERGO pistol grip, a stamped steel stock wrench and a push-button sling swivel. A slip-on rubber butt pad for the M4 Carbine buttstock is available separately.
