MPA’s 57DMG uses a fully machined aluminum lower receiver and fully machined aluminum grips. The machining of the lower and grip reduces weight and increases the level of comfort and ergonomics from the previous design (MPA57SST). Each receiver is laser engraved with the appropriate information. The updated design is compatible with FN57 magazines. This side-cocker has a black Cerakote finish. It comes with a muzzle brake and a scope mount.
