TacStar Slimline Sidesaddle -The Sidesaddle utilizes a non-glare, anodized aluminum backing plate material as our traditional Sidesaddle; however we have contoured the plate so that it takes up less space on the receiver and has fewer areas that could potential snag. Additionally we have changed the shell carrier itself to our proprietary flexible synthetic rubber material, which offers durability and weather resistance as well as secure shell retention. Like the backing plate, the shell carrier also is smaller is size than our traditional sidesaddle, adding to its sleek appearance. 12 Gauge OnlySleek, slimline appearanceStrong, rigid, non glare aluminum backing plateDurable, flexible synthetic rubber shell carrier with secure shell retentionReduced size and streamlined shape reduce chances of snaggingFits: Mossberg 500, 590, Maverick 88
