If you've spent time with a Beretta 1301 and wished the stock offered more adjustability and ergonomic options, this is the bridge you've been looking for. The GG&G BRTTA adapter lets you bolt on a Magpul SGA Remington-pattern stock while keeping your shotgun's receiver completely unmodified. No drilling, no welding, no permanent changes.
You get the precision-machined aluminum adapter, the installation hardware, and something most adapters skip entirely: a spring-tensioned bolt recoil buffer. That buffer is actually the difference-maker here. Beretta engineered a bolt buffer into the factory 1301 design to absorb recoil shock and prevent the bolt from striking the aluminum receiver. The GG&G engineers matched that same concept with their own spring-tensioned design, so the shotgun functions exactly as intended even with the new stock mated to the receiver.
The adapter bridges the receiver profile of your 1301 to the mounting pattern used on Remington 870-style Magpul SGA stocks. Everything is CNC-machined from 6061-T6 aluminum with Type III hard anodized matte black finish, so it's durable and blends visually with modern shotgun builds. Installation takes basic stock removal skills and no modification to the shotgun itself. The matte black finish pairs cleanly with either a tactical build or anything in between.
Many 1301 shooters have wanted the Magpul SGA stock for its adjustable length of pull, spacer system, and overall ergonomic design. Until this adapter, that meant getting creative with fitment or accepting limited options. Now you can run either the Mossberg-pattern or Remington-pattern Magpul SGA, depending on which fits your shooting style. The adapter comes backed by a lifetime GG&G warranty and is made in America.
This specific model is designed for Remington 870-pattern Magpul SGA stocks. GG&G also offers a separate Mossberg-pattern adapter (GGG-2719) if you prefer that stock instead. Each adapter is engineered to match the mounting interface of its respective stock type.
No, the adapter installs completely non-destructively. You'll remove the factory stock using standard procedures, then bolt the new adapter and stock to the receiver. No drilling, welding, or permanent alterations to the shotgun are needed. Installation requires basic mechanical knowledge of stock removal.
The buffer absorbs recoil shock and prevents the bolt carrier from striking the aluminum receiver under firing, which protects the gun's internal components and maintains reliability. Beretta designed a buffer into the factory 1301, and GG&G includes a matched component with this adapter to ensure the shotgun functions safely and correctly with the new stock configuration.
The BRTTA adapter is compatible with Beretta 1301 Tactical in Gen I, Gen II, Gen III, and Mod 2 configurations. It does not fit the Beretta A300 platform, as the operating systems are different. Always verify your specific 1301 model before ordering.
