The Mesa Tactical LEO Gen II Telescoping Stock Adapter for the Mossberg 500 in 12 gauge (brand part no. 92630) lets shooters install AR-15 adjustable buttstocks and pistol grips on the venerable Mossberg 500 platform. The concept is simple: the factory shotgun stock is replaced by an adapter that attaches to the rear of the receiver and mimics the rear of an AR-15 lower receiver, letting a standard AR-15 receiver extension tube thread in. From there, any compatible AR-15 telescoping stock and pistol grip attaches reliably, giving the 500 a fully adjustable, tactical configuration.
