A TruGlo TGTG8955M2 RedDot Sight Mount is a steel adapter built to mount RMR-pattern red dot sights directly to Mossberg 500, 590, 590A1, and 930 shotguns without requiring a Picatinny rail. This mount takes advantage of drilled and tapped receiver holes on Mossberg platform shotguns, letting you add a modern optic to a classic combat or hunting shotgun in minutes—no gunsmithing, no rail installation. The low-mounted design keeps your sight line tight to the receiver, preserving the handling characteristics that make Mossberg shotguns so quick and instinctive in the field or at the range.
Whether you're running a home-defense 590A1, a tactical 930 semi-auto, or a proven 500 hunting gun, adding an RMR to your Mossberg shotgun opens up new options for accurate fire under stress. The compact, lightweight steel construction won't add unnecessary bulk, and the included hardware and installation tools get you mounted and zeroed without extra trips to the shop. The direct-to-receiver design also means zero wobble and zero reliance on external rail systems that can shift or fail.
This is one of those practical upgrades that works because it's straightforward: drill-and-tap holes are already there on most modern Mossberg shotguns, the RMR is a battle-proven optic platform, and TruGlo has engineered a solid, no-nonsense adapter that lets both pieces talk to each other without compromise.
