Jeremy Stafford from Mossberg discusses the 590R and 590RM shotguns, highlighting key design improvements. The firearms feature a safety system similar to the AR-15, making it easier and safer for users familiar with AR-15s. Modifications include a redesigned rear comb, flat-face trigger, extended action release, and improved loading and ejection ports for modern loading techniques.
Essentially, they are very similar. The “RM” signifies the magazine fed version. The “R” versions are also being produced, and there are some variations in the models produced.
The change to a rotary safety was driven by the desire to improve ergonomics, especially when using a pistol grip. The traditional Mossberg top-tang safety becomes less efficient in that configuration. The new rotary safety allows for easier and faster manipulation.
Yes, to a large extent. The design incorporates features that allow for compatibility with many AR-15 style grips and stocks. This was a deliberate design choice to increase customization options.
Magazine-fed shotguns offer faster reloading capabilities compared to traditional tube-fed shotguns. This can be a significant advantage in tactical or defensive situations. Also the ability to change the capacity of the shotgun quickly is a great advantage. The 590RM uses detachable box magazines. And there are different capacity magazines that are available.
Mossberg has taken steps to mitigate recoil. The design, particularly with the optimized stock configuration, aims to provide a more controlled shooting experience. Also a substantial butt pad has been added.
