The Magpul UCS (Universal Carbine Stock) is designed to fit perfectly on weapons equipped with a vertical M1913 Picatinny rail at the rear of the receiver. Ideal for many platforms, it features a reversible hinge that allows it to fold to the left or right, as well as a 5° drop angle for optimal clearance of the cocking handles and ejection ports.
It comes with two exclusive cheek rests (0.50“ and 0.75”) and a reversible M1913 collar offering half-notch height variation, ensuring precise head positioning for perfect alignment with your sights or optics.
With six-position length-of-pull (LOP) adjustment for a total of 3", quickly adjustable via side knobs, it adapts to all shooters, with or without a vest or bulky equipment. The UCS also features a reversible, anti-rotation QD sling attachment point and a 0.70" MOE SL Enhanced rubber recoil pad for added comfort.
