Full Quad Rail System for Mossberg 500 and 590 Shotguns
The Full Quad Rail System for Mossberg 500 and 590 Shotguns allows you to easily and quickly equip and protect your Mossberg 500 or 590 Shotgun to handle mission critical situations like never before possible.
Prepare to be blown away, because this is the real deal. This is the last Mossberg rail you will ever need. As you can see by the pics, the piece is beautiful and entirely functional. The piece now allows any accessory that can fit on a rifle to now be mounted on the Mossberg 500, 590, and Maverick 88 Shotguns. Will not fit 500 and 590A1 without mag tube extension (5-shot models will not work) and 590 bayonet lug gets in the way and must be filed on each side. Rail includes a 1" pipe to take the place of the magazine extension tube, if you do not have a 7 shot tube. Not ideal but works.
The RB7M quad rail system features:
One piece T6 6061 construction
Small 16 ounce weight!!
Type 2 black anodizing
Full install kit with tools
Expect recoil to be cut by 15%
Rail Comes with Mounting Hardware. Accessories not included and Shotgun pictured is not for sale.
Here's the best part. These items are made in America!
No gunsmithing required! This rail will fit both tapped and untapped receivers, both. Install time take under 10 minutes from the time the rail is removed from the box to the time the shotgun is ready to fire. We even supply the tools!
Warning: Never use red loctite on screws and do not overtighten, it holds very well when they are snugged. Never overtighten the Mag clamp as it may bend the tube or limit the follower movement, causing a loading failure.
