NRA Gun of the Week: Mossberg 590M Mag-Fed Shotgun
The most distinctive feature of Mossberg’s latest series of 590 shotguns is a detachable box magazine. Using the 590 platform as a starting point, Mossberg, in conjunction with Adaptive Tactical, modified the 590 receiver to accept detachable box magazines holding five, 10, 15 or 20 rounds of 12-gauge ammunition.
