The UBR 2.0 is an adjustable stock for the AR15/M4, designed to offer the same strength and stability as a fixed stock with a consistent and comfortable cheek weld in any position.
An update of the revolutionary Utility/Battle Rifle (UBR) stock, the UBR 2.0 features a fixed cheek piece to provide a consistent cheek weld in any of its 8 positions, and is compatible with Carbine as well as A5-length buffer systems. Designed to accommodate large bore AR calibers and withstand severe impacts, the UBR 2.0 comes standard with front and rear QD sling attachment points, two footman’s loops, the ergonomic MOE SL™ angled-toe rubber butt-pad, and customizable storage compartment.
