Magpul® UBR® GEN2 Collapsible Stock MAG482

The Magpul UBR GEN2 is a versatile adjustable stock that fits AR15/M4 and AR10/SR25 platforms. It is designed to give the same level of strength and stability as a fixed stock while also offering a comfortable and consistent cheek weld in any position.

This updated Utility/Battle Rifle (UBR) stock version features a fixed cheek piece that ensures a consistent cheek weld in each of its eight positions. It's not just compatible with Carbines, A5, and SR-25 length buffer systems; it's a versatile option for different firearms.

The UBR GEN2 is built to withstand severe impacts and can accommodate large-bore AR calibres. It's almost five ounces lighter than its predecessor but retains the same level of durability, ensuring it's a reliable choice for any firearm enthusiast.

The UBR GEN2 has front and rear QD sling attachment points, two footman loops, and an ergonomic MOE SL angled-toe rubber butt pad. The customizable storage compartment is a bonus.
