Product DescriptionThe Magpul UCS (Universal Carbine Stock) is built for firearms that use a vertical M1913 Picatinny rail at the rear of the receiver for stock fitment. Designed to work around varying charging handle styles, ejection port locations, and control layouts, the UCS features a reversible hinge that supports both left- and right-side folding configurations and incorporates five degrees of drop for added clearance. For improved head placement and sight alignment, the UCS includes two interchangeable cheek risers and a reversible M1913 clamp that allows a 1/2-slot height adjustment. Length of pull is adjustable across six positions to help fit different shooters and gear setups, and the stock includes a reversible anti-rotation quick-detach sling socket plus an enhanced rubber butt-pad for comfort.
