TacStar - a Lyman brand and leader in tactical accessories - has introduced their combination SideSaddle and Rail Mount for Mossberg 12 gauge shotguns. This simple and effective tactical can upgrade Mossberg 500, 590 and Maverick 88 shotguns - no gunsmith needed. Ultra-rigid, this lightweight billet aluminum unit 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 SideSaddle incorporates TacStar's proprietary material for durability and secure shell retention.
