The Mesa Tactical LEO Telescoping Stock Adapter for a Mossberg 500/590A1/Mav88 (93170) replaces the shotgun stock and accepts AR15 buffer tubes allowing for an adjustable stock to be attached to the shotgun. In addition to adding an adjustable stock to the shotgun, it also allows a pistol grip to be connected. The LEO adapter lowers the stock elevation about an inch lower than the High-tube adapters and does not require sighting or aiming aids. The LEO adapter also reduces the length of pull compared to the factory stock. All LEO adapters accept optional push-button sling swivels, and Mossberg 500 LEO adapters can accept stamped steel pocket sling loop and hook loops.
