The Magpul SGA Stock takes a proven pump gun and finally lets it fit you instead of the other way around. Built for the Mossberg 500, 590, and 590A1 12 gauge shotguns (and the Maverick 88), this ambidextrous buttstock is a genuine drop-in replacement. Pull the factory stock bolt, slide the SGA on, torque it back down, and you're done. No gunsmithing, no fitting, no headaches. The bright orange color makes it easy to spot in a safe or on a rack, and it gives an otherwise all-business shotgun a little personality.
The heart of the SGA is its spacer system. Length of pull adjusts from 12.5 inches out to 14.5 inches in half-inch steps using the included spacers, so tall shooters, folks in bulky gear, and anyone running the gun differently can all find their sweet spot. The textured, angled pistol grip area with side panels gives you positive traction and control whether your hands are cold, wet, or sweaty. If you're running an optic or raised sights on a 590A1 top rail, the SGA accepts optional cheek risers in 0.25, 0.50, and 0.75 inch heights (sold separately) to get your cheek weld right behind the glass.
Twelve gauge kicks, and the SGA's angled rubber recoil pad soaks up a real chunk of that felt recoil compared to the hard factory pad. The slight bevel also helps you shoulder the gun fast and clean. On the sling side, you get integral ambidextrous 1.25 inch sling loops recessed into both sides of the stock, so single-point, two-point, and QD setups all work without buying extra hardware.
Made in the USA from reinforced polymer, the SGA weighs in around 1.5 pounds and shrugs off hard use. Owners consistently call out the solid build and durable feel, noting it holds up far better than cheaper aftermarket options.
Yes. The SGA is designed for the Mossberg 500, 590, and 590A1 12 gauge shotguns, and it also fits the Maverick 88. It is not compatible with the Mossberg Shockwave without a stock interface, so stick to the standard stocked models.
It's a true drop-in swap that most folks can knock out at home in a few minutes. You remove the factory stock bolt, slide the SGA into place, and torque the bolt back down using simple hand tools. No fitting or gunsmithing required.
No, the stock ships with a zero-rise comb and the cheek risers are sold separately. Magpul offers them in 0.25, 0.50, and 0.75 inch heights so you can match your eye to the height of your optic or raised sights. If you're mounting glass on a 590A1 top rail, a riser makes a big difference in getting a clean cheek weld.
The angled rubber recoil pad noticeably cuts felt recoil compared to the hard factory buttpad, which makes long range sessions and full days in the field a lot more comfortable. The slight bevel on the pad also helps the gun shoulder quickly. It won't turn buckshot into a .22, but the difference is easy to feel.
