The UBR GEN2 is an adjustable stock for AR15/M4 and AR10/SR25 platforms, designed to offer similar 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 GEN2 features a fixed cheek piece to provide a consistent cheek weld in any of its eight positions and is compatible with Carbine as well as A5 and SR-25 length buffer systems. 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.
