The TacStar SideSaddle shotgun rail mount is a simple and effective tactical upgrade for 12 gauge Remington 870, 1100 and 11-87 shotguns - no gunsmith needed. Ultra-rigid, this innovative lightweight aluminum rail mount from TacStar straddles both sides of the receiver and is crafted with a non-glare anodized finish. The top Picatinny rail can mount a variety of accessories, yet is designed to sit just high enough to allow continued use of the shotgun's bead sight. Keeping six shells in readiness, the low profile design of the rail incorporates TacStar's proprietary material for durability and secure shell retention. Specifications: - gauge: 12 gauge Mossberg 500 and 590 - finish: anodized non-glare - rail type: Picatinny..
