The Magpul UBR Gen2 collapsible stock for AR-15, M16, and M4 platforms brings precision adjustability to your rifle without compromising stability. Where many shooters settle for a fixed position, the UBR Gen2 delivers eight different length-of-pull positions—each with a fixed cheek piece that maintains a consistent, repeatable cheek weld. That consistency matters at distance and in unpredictable field conditions: your sight picture stays the same whether you're in full extension or fully collapsed. Built lighter than the original UBR while retaining the same legendary durability, this stock is engineered to handle high-round-count sessions and severe impacts without flex or rattle.
The UBR Gen2 works with standard carbine-length buffer systems and is also compatible with A5 and SR-25 length systems, making it adaptable across different AR builds and configurations. The included custom receiver extension tube is designed for rigidity and precise positioning across all eight detents. You get two sling attachment points (front and rear QD loops), two footman's loops for gear attachment, and a customizable storage compartment built into the buttstock—practical features that make this stock do more than just adjust length. The MOE SL rubber butt-pad offers genuine ergonomic shaping and impulse absorption.
Built in the U.S.A. from synthetic materials proven in duty and competition use, the Flat Dark Earth finish is a professional middle ground—neutral enough for any mission, distinctive enough to stand out in a safe. Whether you're building a precision rifle, reconfiguring a duty AR, or just want the flexibility to fit different shooters and clothing layers, the UBR Gen2 is a no-compromise adjustable option.
