Description
The Magpul SGA Stock takes the classic Remington 870 12 gauge and brings it into the modern era of fit and feel. It's a true drop-in replacement for the tired factory stock, and it swaps in with basic tools in a few minutes. No gunsmithing, no fitting, no headaches. The bright orange polymer construction makes it stand out, and the reinforced build gives it that solid, no-rattle feel that folks who've run the factory stock will appreciate right away.
Why the SGA Stock Changes How Your 870 Handles
The biggest win here is the ambidextrous, user-configurable design. The included spacer system lets you set the length of pull anywhere in the roughly 12.3 to 14.3 inch range, so you can run it short for close-quarters work or heavy clothing, or stretch it out for a comfortable clays setup in a t-shirt. The angled pistol-grip area with textured side panels gives you real traction and control, and the recoil-reducing butt-pad has a slight bevel that helps the gun shoulder fast and stay put under recoil.
Setting Up the SGA for Optics and Cheek Weld
The SGA ships with a pre-fitted zero-rise comb, but it's built to accept optional Cheek Risers in 0.25, 0.50, and 0.75 inch heights (sold separately). That's a big deal if you're running a receiver-mounted red dot, since the factory stock sits too low to get your eye lined up properly. Add a riser and you get a proper cheek weld that puts you right behind the glass.
Sling Options Built Into the SGA Stock
Magpul molded integral 1.25 inch sling loops into both sides of the stock, so you've got ambidextrous, low-profile attachment points ready to go without bolting on extra hardware. Between the fit adjustments, the improved grip, and the sling flexibility, this is one of the most popular aftermarket upgrades you can make to an 870. Made in the USA.

Frequently Asked Questions
Does the Magpul SGA Stock fit any Remington 870?
It's designed for 12 gauge Remington 870 shotguns and works across common variants like the Express, Express Tactical, Express Synthetic, Wingmaster, and Police Magnum. It does not fit 20 gauge 870s or the TAC-14, which doesn't use a traditional stock. If your 870 is a standard 12 gauge with a normal stock bolt, you're good to go.
How hard is the SGA Stock to install?
It's a true drop-in job with no gunsmithing required. You remove the factory stock bolt, slide the SGA on, and torque the bolt back down with simple tools. Most people have it done in under ten minutes, and a lot of folks say it makes an older 870 feel like a brand new gun.
Can I use the SGA Stock with a red dot or optic?
Yes, that's one of the reasons people choose it. The stock comes with a zero-rise comb and accepts optional cheek risers in 0.25, 0.50, and 0.75 inch heights (sold separately). Adding a riser raises your cheek weld so your eye lines up with a receiver-mounted optic, something the factory stock can't manage.
How does the length-of-pull adjustment work on the SGA?
The SGA uses an included spacer system that lets you tune length of pull across roughly 12.3 to 14.3 inches. You add or remove spacers to dial in the fit, which is great for sharing the gun between different shooters or adjusting for heavy clothing versus a t-shirt. It's a simple, solid setup with no wobble once it's snugged down.
