I’m tempted to call shenanigans on this one. The Mossberg 590 shotgun has been on the market for years. It’s a good reliable safe choice for those who want a scattergun. This year, Mossberg decided to flip the bird to the ATF and release a shortened version of the firearm that (like the Franklin Armory XO-26) escapes the normal definitions of a “shotgun” without running afoul of the National Firearms Act. Nevertheless despite the fact that this is just a 590 that went on a diet, the readers have spoken. The Mossberg Shockwave is the 2017 TTAG Reader’s Choice for Best New Shotgun of 2017.
