The Magpul SGA is a fixed shotgun stock for Remington 870 12-gauge shotguns, replacing the factory stock on standard stock hardware.
The Magpul SGA Stock for Remington 870 (MAG460) rebuilds the 870's rear end around fit and control. Spacer-based length-of-pull adjustment lets you match the stock to your frame and clothing — critical on a shotgun, where a stock even an inch (25 mm) too long slows the mount and amplifies recoil — while the recoil-absorbing buttpad soaks up heavy loads and slugs.
The near-vertical grip geometry improves trigger-finger mechanics and keeps the wrist neutral on a low-mounted gun. Molded from reinforced polymer, compatible with optional cheek risers for optic use and equipped for sling mounting, the SGA is the definitive furniture upgrade for working 870s.

Compatibility & Fitment
Fits Remington 870 12-gauge shotguns using standard stock hardware. It is a different part number from the Mossberg SGA, so make sure you order the one that matches your action; if you have a less common 870 configuration, get in touch with the model details before you buy.

Frequently Asked Questions
Is this the right SGA for a Remington 870?
Yes, the MAG460 is the 870-specific version and fits Remington 870 12 gauge shotguns. It is a different part number from the Mossberg SGA, so make sure you are ordering the one that matches your action. If you have a less common 870 configuration, get in touch with the model details before you buy.
What does the SGA change about how the 870 handles?
It keeps the traditional shotgun stock shape rather than switching to a pistol grip, so your mount and cheek weld stay familiar. What it adds is a length of pull that you can set with spacers, so the gun fits you rather than the other way around. A cushioned buttpad also helps with the recoil of full-power 12 gauge loads.
How much adjustment is there and what tools are needed?
Length of pull is changed by adding or removing spacers behind the buttpad, which is a simple job with ordinary hand tools. Set it so that when the gun is mounted the comb sits under your cheekbone without you stretching for the trigger. Try it in the clothing you actually shoot in, as a heavy jacket effectively shortens the pull you need.
Which finishes are offered and is there a matching forend?
Black, Flat Dark Earth, Stealth Gray and Orange are available. The MOE M-LOK forend for the 870 is the natural partner if you want M-LOK mounting up front and matching furniture.
