Product DescriptionThe TacStar Shotgun Rail Mount with SideSaddle is an ultra-rigid, lightweight upgrade for 12-gauge Mossberg 500 and 590 shotguns. Machined from durable aluminum with a non-glare hardcoat anodized finish, it straddles both sides of the receiver for maximum stability. A raised Picatinny rail on top allows mounting optics or accessories while maintaining use of standard bead sights.
