Due to the overwhelming popularity of our stock adapter for the Stoeger shotguns, we are introducing the same innovative product for the Franchi Affinity-Series 12ga shotgun as well! The machined 6061T6 Aluminum spacer and steel thread adapter allows the use of the Magpul Mossberg 590 SGA stock on the Franchi Affinity series 12ga shotguns. Chrome-moly internal threaded insert converts factory 12mmx1 stock bolt thread to the Magpul’s 5/16-18 SAE thread. Matte Black anodized outer spacer creates a smooth transition between the Franchi receiver and the Magpul stock. Still allows use of the factory stock shims for cast and drop adjustment! Drop-in parts, no fitting required. STOCK NOT INCLUDED. NOTE- ONLY WORKS WITH MAGPUL MAG590-series SGA stocks intended for the Mossberg 500/590/590A1 shotguns! Does NOT fit the Remington model.

While this was designed specifically for the Magpul SGA stock to take advantage of the wide range of adjustability, it will work with all Mossberg 500/590 aftermarket stocks although some will require minor fitting. The adapter adds approx. 1/2″ to the length of pull of Mossberg stocks when used on the Franchi.
