The Mesa Tactical LEO Gen II is a best-selling stock adapter that features an optimal stock elevation allowing the use of iron sights or even the bead sight, making it ideal for shooters who want to retain their standard sight picture. This adapter allows AR-15 style buttstocks and pistol grips to be used with Mossberg 500/590 shotguns by replacing the shotgun stock with an adapter that attaches to the rear of the receiver and mimics an AR-15 lower receiver, into which an AR-15 receiver extension tube can be threaded, after which the AR-15 telescoping stock and pistol grip can be reliably attached.
Built from investment cast aircraft grade aluminum, CNC machined and powdercoated black with a tough, chemical resistant finish, the LEO Gen II delivers durability for professional and tactical applications. The adapter features adjustable length-of-pull (LoP) to fit shooter’s stature or for use with body armor and other equipment. The design gives the shotgun similar handling characteristics to the AR-15, while the collapsible stock makes the shotgun easier to stow, transport and deploy, and the pistol grip configuration allows increased control and user comfort.
The LEO Gen II Telescoping Stock Adapter installs easily without gunsmithing, and includes sling attachment points. Whether you’re outfitting a duty weapon or upgrading a personal defense shotgun, this adapter transforms your Mossberg platform into a modern, ergonomic tactical system.
