MAGPUL UNIVERSAL CARBINE STOCK FDE

The Magpul Universal Carbine Stock in FDE is a fully adjustable rear stock designed for modern carbines and tactical rifles built on M1913 Picatinny rails instead of traditional buffer tubes. Whether you're running a short-barreled rifle, a non-AR platform, or experimenting with unconventional setups, this stock delivers the kind of shooter-configurable adjustments you'd expect from Magpul's Pro Series line—without the complexity or the need for tools.

What sets the UCS apart is its adaptability across platforms. It works on any receiver with an M1913 rail: SIG MCX and MPX, FN SCAR, IWI Galil, CZ Scorpion, Ruger LC Carbine, and AK variants. A reversible hinge lets you fold left or right to match your charging handle and ejection port layout. The 5-degree drop angle clears most controls without forcing your grip or sight picture out of whack. You get three inches of length-of-pull adjustment across six positions—all of it push-button activated—so the stock fits shooters built different, whether you're running plate carrier armor or running light.

The cheek riser system is where the UCS really earns its name. Two reversible risers (0.50" and 0.75") stack with a reversible M1913 clamp that adds another half-slot of height adjustment, letting you dial in your head position to your optic or iron sights without shims or tape. A reversible QD socket handles sling attachments without rotation, and the stock accepts Magpul MOE SL and DT Butt-Pads for personal preference. Made in the USA, weighing just 1.1 pounds, and built to handle the kind of tinkering that makes rifle customization actually worthwhile.

Frequently Asked Questions

What firearms is the Magpul Universal Carbine Stock compatible with?

The UCS is designed for any rifle or carbine with an M1913 rail on the receiver rear, including SIG MCX/MPX, FN SCAR, IWI Galil, CZ Scorpion, Ruger LC Carbine, PSA AK/AK-V, and other M1913 rail-equipped platforms. Exact length-of-pull ranges vary by platform; common ranges span 11–16 inches depending on the specific firearm.

Can I adjust this stock without tools?

Yes. The length-of-pull adjustment uses push buttons to cycle through six positions. The cheek risers are removable and reversible without tools. However, installation to your receiver's M1913 rail will require appropriate mounting hardware for your platform.

What do the cheek risers do, and are they removable?

The two reversible cheek risers (0.50" and 0.75") adjust your head placement and comb height for a better sight picture with your optic or iron sights. They are toollessly removable and reversible, and when combined with the reversible M1913 clamp, allow you to fine-tune your shooting position across multiple axes.

Can I fold this stock, and which direction?

Yes, the UCS features a reversible folding hinge that allows you to configure it for left or right folding, depending on your charging handle and ejection port layout. The 5-degree drop angle prevents binding with common controls.
