The factory stock on a Remington 870 works fine, but it was never built to fit everyone. The Magpul SGA Stock changes that by giving you a buttstock you can tune to your body, your gear, and the way you actually run the gun. It is a true drop-in swap that adds real adjustability to one of the most trusted pump shotguns ever made.
The heart of the SGA is its spacer system. Using the included spacers, you can adjust length of pull in half-inch increments across roughly a 12.3 to 14.3 inch range, so a smaller-framed shooter can cycle the action without overreaching and a taller one can stretch it out for a natural mount. That same flexibility makes it easy to share one shotgun across a household or shorten things up when you are running heavy clothing. The angled grip area is textured with side panels for solid traction and control, and the recoil-reducing butt-pad takes some of the bite out of 12 gauge loads.
Magpul built this stock specifically for the 12 gauge Remington 870, and it shows in the fit. Installation is straightforward with basic tools, no gunsmithing required, and the reinforced polymer construction holds up to hard range and field use. Owners consistently point out that it sits square on the shoulder instead of at an odd angle the way some off-brand stocks do.
If you run a red dot or raised sights, the SGA supports optional cheek risers (sold separately) that lift your comb height for a proper cheek weld and sight alignment. It also has integral, ambidextrous 1.25 inch sling loops recessed into both sides, so lefties and righties get the same clean setup. Made in the U.S.A., it is one of the most popular upgrades you can bolt onto an 870.
It is designed for 12 gauge Remington 870 shotguns and fits the common variants like the Express, Express Tactical, Express Synthetic, and Police Magnum. It does not fit 20 gauge 870s or the TAC-14 since that model has no traditional stock. If you are running a standard 12 gauge 870 with a full stock, you are good to go.
It is a true drop-in swap that most people finish in a few minutes with basic tools. You remove the factory stock bolt, slide the SGA on, and torque the bolt back down. No gunsmithing or fitting is required.
Yes. The stock accepts optional cheek risers that raise your comb height to line your eye up with a receiver-mounted optic or raised sights. The risers are sold separately, but the base stock is built to accept them when you are ready.
Using the included spacers, you can set length of pull in half-inch increments across roughly a 12.3 to 14.3 inch range. That makes it easy to fit smaller or larger shooters, adjust for heavy clothing, or share one shotgun in a household. It is one of the main reasons folks pick this stock over the factory unit.
