The Magpul UBR Gen2 (Utility/Battle Rifle) stock (brand part no. MAG482-ODG) is an adjustable stock built for AR-15/M4 and AR-10/SR25 platforms that delivers the strength and stability of a fixed stock while still collapsing for transport and storage. Molded in OD Green, it carries a fixed cheek piece that holds a consistent, comfortable cheek weld across all eight of its positions, and it’s compatible with Carbine, A5, and SR-25 length buffer systems, so it drops onto a wide range of AR builds. Front and rear QD sling attachment points, two footman’s loops, the ergonomic MOE SL angled-toe rubber butt-pad, and a customizable storage compartment round out a stock built for serious, repeatable use.
