We’ll in that situation the military would give me one. And if I really needed that much ruggedness I’d rather have steel Remington 870 anyway instead of the aluminum Mossberg.
Well, that’s what/who the 590 series was designed for. As far as steel vice aluminum receivers, the M590 won against about five other makers offerings about 20+ years back, Rem, Win, Benelli ( the USMC adopted one of those for a while too) and the Mossy won the overall competition, including durability reliability etc.
It has been the Army shotgun for sometime. I carried one in my vehicle in IRQ in 2003 and 4. Made a difference in the crowds. Good driving suppression weapon, but the go to was still the M4 or A2.
