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-ga. ammunition. This new iteration, the 590M, is reliable and fast to load. Learn more about the Mossberg 590M in our latest NRA Gun of the Week video.
