Magpul | Magpul UCS | Black

The Magpul UCS (Universal Carbine Stock) is built for rifles using a M1913 Picatinny rail at the rear of the receiver instead of a standard buffer tube, offering 3 inches of length‑of‑pull adjustment across six positions via intuitive push‑buttons. A reversible hinge folds to either side, a 5‑degree drop improves clearance for different charging handle and control layouts, and two reversible cheek risers (0.50 and 0.75 inch) dial in comb height for iron sights or an optic. A reversible, anti‑rotation QD socket and compatibility with Magpul's MOE SL and DT butt‑pads round out a stock built specifically for the 1913‑rail platforms a standard AR buffer‑tube stock can't mount to.
