The factory Beretta 1301 stock gets the job done, but a lot of folks want the adjustability and grip feel of a Magpul SGA. That's exactly what this GG&G adapter is built for. It's the Mossberg-pattern version, so it lets you mount a Magpul SGA Mossberg 500/590/590A1 stock straight to your 1301 receiver. No cutting, no drilling, no permanent modification to the gun.
The kit bridges the gap between the Beretta receiver and a stock that was never designed to fit it. GG&G machines the adapter from 6061-T6 aluminum and finishes it with a Type III hard anodized matte black coating, so it holds up to weather and hard use. Inside the kit you also get a spring-tensioned bolt recoil buffer made from 4130 steel. That buffer is the important part a lot of people overlook. It closely mirrors the buffer Beretta engineers put in the factory 1301 stock, cushioning the bolt under recoil so it doesn't hammer the rear of the aluminum receiver. Skip a buffer and you risk real operational damage down the road, so it's good that GG&G includes one.
The SGA Mossberg stock is an ambidextrous, user-configurable buttstock with a spacer system that lets you dial in length of pull to fit you or anyone else who shoulders the gun. It's known for improved grip ergonomics, and Magpul offers optional cheek risers if you're running an optic and need a higher sight line. This adapter setup also plays nice with GG&G's 1301 rear sling attachments, and the Magpul MAG492 receiver sling mount works with it too.
Installation is manageable if you're comfortable with basic stock removal. It fits Beretta 1301 Tactical models, and everything you need to complete the conversion comes in the box. Made in the USA and backed by a GG&G lifetime warranty.
This is the Mossberg-pattern version, so it accepts the Magpul SGA Mossberg 500/590/590A1 stock. If you want to run the Remington 870-pattern SGA instead, GG&G makes a separate adapter for that. Double-check which SGA stock you already own before ordering.
No. The kit is designed to fit the 1301 receiver without any permanent modification to the gun. As long as you're comfortable with basic stock removal, installation is straightforward, and everything you need comes in the box.
The factory Beretta 1301 stock houses a buffer that absorbs the shock of the bolt under recoil and keeps it from slamming the rear of the aluminum receiver. When you swap to an SGA stock, you lose that factory buffer, so GG&G supplies a spring-tensioned replacement. It's a critical part for protecting your receiver and keeping the gun running right.
Yes. The Magpul SGA Mossberg stock ships with a spacer system that lets you tune length of pull to your build, which is one of the main reasons people make the switch. Magpul also offers optional cheek risers if you're running an optic and need a higher cheek weld.
