The UBR GEN2 Stock fits AR15/M4 and AR10/SR25 platforms and includes technologies that provide LOP adjustability combined with a fixed, consistent cheek weld, fixed stock stability, and extra storage. At the heart of the UBR GEN 2 is a custom receiver extension that provides the secure mounting that’s critical for stability and durability. Designed to handle big bore recoil and severe impacts, the UBR GEN2 is excellent for hard-use scenarios where flexibility and survivability are a must.

Made in the USA.
