(4 customer reviews)


Machined 6061T6 Aluminum spacer and steel thread adapter allows the use of the Magpul Mossberg 590 SGA stock on the Stoeger M3k/M3000/M3500/P3000 series 12ga shotguns. Chrome-moly internal threaded insert converts factory 10mmx1 stock bolt thread to the Magpul’s 5/16-18 SAE thread. Matte Black anodized outer spacer creates a smooth transition between the Stoeger 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 MAG490-series SGA stocks intended for the Mossberg 500/590/590A1 shotguns! Does NOT fit the Remington model. It may work with other stocks intended for the Mossberg 500/590, but some minor fitting may be required.

    Works great with solid fitment. The lines match up nice with the receiver and the stock. I didn’t think the SGA stock looked like anything special, but glad I tried it out. Got it to fit me perfectly thanks to this kit.

    Love this upgrade to my M3K. Very well machined with no fit / installation issues. I was amazed how easy / well the shotgun points / comes into position with the SGA stock and this adapter. No additional shimming was needed to make it fit perfectly. The SGA stock also adds a little more mass to balance the gun and I really prefer the grip angle over the factory stock. It also looks really cool 🙂

    Very easy install. Nearly seamless interface between gun and stock.
    The Magpul stock is just a great addition to my M3K shotgun and totally changes the feel of the gun.
