Magpul® UCS™ - Universal Carbine Stock
The Magpul Universal Carbine Stock (UCS) is engineered as the ultimate upgrade for firearms featuring a vertical M1913 Picatinny rail at the receiver’s rear for stock attachment.
Designed to adapt to a wide range of charging handle styles, ejection port positions, and control configurations, the UCS offers a reversible hinge for left or right folding and a 5-degree drop for enhanced clearance.
Included are two reversible cheek risers (0.50" and 0.75") paired with a reversible M1913 clamp, providing a 1/2-slot height adjustment to fine-tune head placement for optimal sight alignment with iron sights or optics. With three inches of length-of-pull (LOP) adjustment across six positions, easily adjustable via intuitive LOP buttons, the UCS accommodates any shooter, whether wearing body armor or operating in minimalist setups.
The UCS features a reversible, anti-rotation QD socket for secure sling attachment and is compatible with Magpul’s MOE SL® and DT Butt-Pads for added customization. Proudly made in the USA, this stock delivers unmatched versatility and durability.
