The Magpul UBR Gen 1 stock is the perfect upgrade to your service rifle. The UBR is a heavy duty stock with 7 position at .56” intervals which extends ½” longer than an A2 Stock. The UBR is also one of the heaviest adjustable stocks on the market at 1.46 lbs. The modular design offers the stability of a fixed stock with the consistent cheek weld in any position. This is the most robust collapsible stock we have ever used.
*NOTE: This is the official Magpul UBR Gen 1 which has been discontinued by Magpul.
The UBR includes the required extension tube and mounting hardware. It DOES NOT include a M4 carbine buffer and spring which are required for use with the UBR. (7.62x51 ARs may require the use of a custom short buffer and spring.)
