Product DescriptionThe MasterPiece Arms BA Series one-piece scope mount is engineered to secure high-performance optics to bolt-action rifles equipped with Picatinny rail bases. Built from rugged 6061T6 aluminum with a Type III hard-coat mil-spec anodized finish, this mount uses horizontal split rings and a superior clamping surface for maximum rail engagement. The 30mm tube, 1.125-inch height, and 0 MOA cant deliver a true, repeatable zero, while multiple locking lugs provide absolute return to zero when moving the optic between rifles. With over 3.5 inches of rail interface, the BA mount locks up solidly and is designed to accommodate large objective lenses (up to 50mm for 30mm mounts).Product Highlights One-piece BA mount for bolt-action rifles with Picatinny rail bases 30mm tube, 1.125-inch height, and 0 MOA cant for precise, repeatable zero Precision-machined 6061T6 aluminum with Type III hard-coat mil-spec anodized finish Horizontal split rings and superior clamping surface for maximum rail engagement Over 3.5 inches of rail interface; includes mounting hardware Specs Model: MPA BA Bolt Action Mount Tube Diameter: 30mm Mount Height: 1.125 in Cant: 0 MOA Mount Type: Picatinny rail Material: 6061T6 aluminum Finish: Type III hard-coat mil-spec anodized, black Rings Included: Yes Includes: Mounting hardware Length: 4.76 in Color: Black Intended Use: Bolt-action rifle optics mounting Brand: MasterPiece Arms MPN: BAMOUNT301125 UPC: 866803040144 Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
