GG&G Brtta Stk Adpt Mpul Sga

The GG&G Brtta Stk Adpt Mpul Sga is a precision stock adapter designed for Beretta 1301 shotgun owners who want to upgrade from factory ergonomics to the proven Magpul SGA platform. This adapter solves a critical compatibility gap: it enables shooters to retrofit either the Magpul Remington 870 or Magpul Mossberg SGA stocks onto their Beretta 1301, providing superior ergonomics, modularity, and control. Law enforcement and civilian tactical shooters have long recognized that the factory Beretta stock lacks the adjustability and ergonomic refinement of aftermarket options, making this adapter an essential upgrade for serious operators.

Built by GG&G, Inc.—a manufacturer with deep roots in tactical hardware—this adapter maintains the structural integrity and reliability demands of law enforcement and military shotgun platforms. At just 0.25 lbs and measuring 6.5 x 1 x 8.5 inches, it installs cleanly without adding significant weight or bulk to the platform. The adapter interfaces seamlessly with Magpul SGA stocks, which feature adjustable length-of-pull, multiple sling attachment points, and intuitive safety lever positioning. This design enables shooters to customize their weapon system for individual body dimensions and mission requirements while maintaining the rock-solid reliability the 1301 platform demands in high-stress environments.

This adapter is purpose-built for Beretta 1301 operators—whether patrol officers, entry team members, or professional civilians—who refuse to compromise on ergonomics and weapon control. Installation is straightforward, requiring no permanent modifications to the shotgun. The adapter maintains full compatibility with the 1301's action and gas system, ensuring zero impact on reliability or function. Shooters transitioning from Remington 870 or Mossberg platform training particularly benefit from this solution, as it reduces manual-of-arms inconsistencies and leverages familiar stock controls across their tactical arsenals.
