One Stock to Rule Every Platform

In a world full of rifles, carbines, and PDWs, finding a stock that plays nice with them all isn’t just rare—it’s practically mythical. Enter the Magpul UCS (Universal Carbine Stock), a purpose-built solution for any firearm outfitted with a rear-mounted M1913 Picatinny rail. Whether you’re running a classic AR platform, a modern subgun, or a custom-built hybrid, the UCS adapts with authority—without compromise.

Engineered for Total Modularity

The UCS isn’t just “universal” in name—it’s designed from the ground up to morph to the shooter, not the other way around. Its six-position length of pull (LOP) adjustment offers a full three inches of extension, all controlled via sleek, push-button selectors. Whether you’re wearing body armor, minimalist gear, or just rocking a slick range setup, this stock conforms to your needs.

Need to dial in your cheek weld? You’ve got options. Each UCS ships with two tool-free, reversible cheek risers—in 0.50” and 0.75” heights—so you can customize your comb height for a perfect sight picture, regardless of optic height or iron sight setup.

Built to Flex, Fold, and Fit

Clearance issues? Magpul’s already thought ahead. A reversible folding hinge lets you choose a left or right-side folding configuration—perfect for working around various charging handle styles, ejection ports, and receiver layouts. The 5-degree drop angle adds another layer of smart geometry, ensuring smooth operation on nearly any setup.

Plus, the reversible M1913 mounting clamp allows for ½-slot vertical adjustment, letting you micro-tune stock alignment for your platform of choice.

Mission-Ready by Design

Whether you’re slinging the rifle across your chest or transitioning between shoulders, the anti-rotation QD sling socket (yes, it’s reversible too) gives you dependable attachment options. The UCS is also compatible with Magpul’s MOE SL® and DT series butt-pads, allowing shooters to tailor the rear-end feel to their mission, recoil management, or ergonomic preference.

Available soon in Black and Flat Dark Earth (FDE), the Magpul UCS will retail at $219—and considering its all-in-one adaptability, that’s a worthy investment in performance-driven design.
