New Mossberg 590R Shotgun With Rotary Safety

Mossberg has just updated its tactical shotgun lineup with four new models, all based around a long-respected pump-action design. The new Mossberg 590R introduces a rotary safety to the lineup, and there’s even a new mag-fed version of the shotgun as well.

However, the tang safety makes it harder to use pistol grip furniture with the Mossberg design, so as the demand for tactical shotguns heats up, so does the interest in a shotgun designed with a different safety.

Also, if you want to use a shotgun as a Masterkey-style attachment underneath a tactical rifle, a tang safety mounted atop the shotgun is obviously a no-go, as you can’t use it with the rifle’s chassis in the way. A rotary safety on the side of the gun allows this type of use.

Mossberg remixes the 590 formula again, and as a result, we get four models: The 590R (the base model, with standard muzzle, 6+1 tube mag and collapsible AR-style stock); the 590R Stand-Off (with a stand-off style muzzle attachment, for breaching purposes); the 590RM (fed from a double-stack detachable magazine!) and the 590RM Stand-off (with, again, a stand-off muzzle attachment).
