Product DescriptionThe Mesa Tactical SureShell Polymer Carrier with Saddle Rail combines a rugged 6-shell side saddle with a receiver-mounted Picatinny optics rail for a streamlined, mission-ready upgrade. The shotshell carrier uses glass-filled polymer shell holders secured to the receiver with a lightweight aluminum back plate and brass threaded inserts for strength and longevity. An innovative dual rubber friction system helps keep shells firmly retained under recoil while still allowing fast access. The integrated 4 3/4-inch Picatinny rail is machined from aircraft-grade 6061-T6 aluminum and finished with a mil-spec hard-anodized, non-glare matte finish, providing a robust platform for mounting compatible optics and accessories. Built to MIL-STD-1913 Picatinny specifications, the system installs without gunsmithing and positions the 6-round carrier on the left side of the receiver.Product Highlights 6-round SureShell polymer side saddle keeps extra 12-gauge shells secured and ready Dual rubber friction retention system helps prevent shells from loosening during recoil Integrated 4 3/4-inch MIL-STD-1913 Picatinny rail for optics and accessory mounting Aircraft-grade 6061-T6 aluminum rail with hard-anodized, non-glare matte finish No-gunsmith installation using a lightweight aluminum back plate with brass threaded insertsSpecs Brand: Mesa Tactical Product Line: SureShell Polymer Carrier with Saddle Rail Compatibility: Mossberg 500 / 590A1 / Maverick 88 (12 Gauge) Shell Capacity: 6 shells Mount Side: Left side of receiver Rail Type: Picatinny (MIL-STD-1913) Rail Length: 4 3/4 in Carrier Material: Glass-filled polymer (injection molded) Rail Material: 6061-T6 aluminum Back Plate: Lightweight aluminum with brass threaded inserts Finish: Hard anodized, non-glare matte MPN: 94880 UPC: 878405004424Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
