The Magpul UCS (Universal Carbine Stock) is designed to be the ideal supplement to the wide array of firearms utilizing a vertical M1913 Picatinny rail on the rear of the receiver. To accommodate a variety of charging handles styles, ejection port locations, and control locations, the UCS features a reversible hinge for left and right folding configurations, and five degrees of drop for clearance.

The UCS ships with two exclusive Cheek Risers (0.50ʺ, and 0.75ʺ) and, when combined with the reversible M1913 clamp (allowing for a 1/2-slot height adjustment), the shooter can dial in head placement for an optimal sight picture using iron sights or optics.

Offering three (3) inches of length of pull (LOP) adjustment spanning six (6) positions – which can be changed via the LOP buttons on the sides – the stock fits any shooter, with and without armor or other bulky equipment. The UCS also includes a reversible, anti-rotation QD socket for sling attachments, and features the MOE SL® Enhanced Rubber Butt-Pad, 0.70″ for user comfort.

Made in the USA.
