Gg&G Brtta 1301 He509T Mnt 1/2 Ghst

The GG&G BRTTA 1301 HE509T mount is a purpose-built optic rail designed to fit the Beretta 1301 shotgun and accommodate the Holosun HE509T reflex sight. If you're mounting a red dot on a 1301 and want to co-witness backup iron sights, this aluminum rail delivers a solid platform that keeps your sight picture fast and your profile manageable. The 1301 has become a favorite among hunters and tactical shotgun users alike, and adding a quality reflex optic with dedicated backup sights is a proven way to improve target acquisition without sacrificing reliability.

Built from 6061-T6 billet aluminum, this mount is engineered for durability and precision. All edges are smoothed and rounded—a detail that matters when you're operating a shotgun in close quarters or field conditions. The aluminum components wear a Type III hard coat anodized finish per Mil-Spec, and steel parts are finished in manganese phosphate for a non-reflective, combat-grade appearance. GG&G doesn't cut corners on materials or manufacturing, and that shows in the execution here.

The mount comes with your choice of full or half ghost ring backup sights, so you can configure it to match your shooting style and sight picture preference. Whether you're running the 1301 for hunting, home defense, or tactical training, having that redundancy built in—red dot up front, co-witnessing irons ready to go—gives you options if something goes wrong. It's the kind of practical thinking that separates a gun that works from a gun that works when it matters.

GG&G designed every edge to be smoothed and rounded for shooter safety, and the materials and manufacturing process (billet aluminum, Mil-Spec finishes) are built for field and tactical conditions. This is a purpose-built accessory, not a compromise.
