Tacstar's shotgun rail mount with sidesaddle is ultra-rigid lightweight and straddles both sides of the receiver. It is constructed of aluminum 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. This model is compatible with Mossberg 930.Type: Saddle MountModel: Sidesaddle Rail MountStyle: 1-PieceFinish: Black Hard Coat AnodizedMaterial: AluminumPieces: 1Gun Type: Shotgun
