Magpul UBR Gen2 Universal Carbine Stock – AR-15/AR-10 Mil-Spec/Commercial

The Magpul UBR Gen2 (Utility/Battle Rifle) Stock in OD Green delivers exceptional cheek weld consistency and recoil management through its rigid, non-collapsible design. Unlike traditional collapsible stocks, the UBR Gen2 uses an internal adjustment mechanism that maintains continuous contact with the buffer tube, eliminating play and providing a stable shooting platform for precision and rapid-fire applications. The stock's forward-biased weight distribution helps balance carbine-length rifles and reduces muzzle rise during strings of fire.

Machined from reinforced polymer with an integrated rubber recoil pad, the UBR Gen2 fits both mil-spec and commercial buffer tubes without adapters. The seven-position length-of-pull adjustment is secured by a side-mounted lever, and dual water-resistant battery storage tubes are built into the stock body. Two 1.25-inch QD sling mounts (one ambidextrous rear, one left-side) provide flexible carry options. Installation requires a standard carbine castle nut wrench and takes approximately 10 minutes.
