The factory-integral muzzle brake and barrel porting are defining features of this Mark XIX, designed to help manage the .50 AE’s recoil impulse. The 6-inch stainless barrel uses polygonal rifling with a 1:19 RH twist, pairing clean internal finish with consistent bullet engagement.
Its operating system is single-action and gas-operated, with a rotating multi-lug bolt. The external hammer and ambidextrous slide-mounted safety levers provide familiar controls, while the fixed combat sights—ramped front blade and notch rear—deliver a simple, durable sight picture.
Construction is all stainless steel, including the frame, receiver, and slide, with brushed flats and matte rail surfaces. A full-length top rail runs the barrel, and an accessory rail is integrated into the dustcover for mounting compatible gear. Black textured grips with MRI eagle medallions round out the factory configuration.
This .50 AE Mark XIX is configured as a 7+1 capacity, full-size pistol. Visible rollmarks confirm "MADE IN USA, MAGNUM RESEARCH INC., PILLAGER, MN USA," and the example presented is made in USA. The package includes one 7-round steel magazine and the original Magnum Research molded hard case.
