Magpul Ubr Gen 2 Adj Stk Ar15/m4

The Magpul UBR Generation 2 Adjustable Stock for AR15/M4 and AR10/SR25 platforms delivers the rigidity of a fixed stock with the versatility of eight adjustable positions. Purpose-built for operators, LEOs, and precision shooters who demand consistent cheek weld geometry across varied shooting positions and body armor configurations, the UBR Gen 2 combines proven Magpul durability with practical ergonomics. Its fixed cheek piece maintains proper sight picture and scope eye relief regardless of which of its eight length-of-pull positions is selected.

Compatibility spans multiple buffer tube standards: Carbine, A5, and SR-25 length systems, making the UBR Gen 2 adaptable across M4 carbines, rifle-length uppers, and large-bore AR platform builds. The stock's robust construction accommodates the recoil impulse of magnum cartridges without flex or rattle. At 1.88 lbs and measuring 11.5 inches in maximum length, it adds minimal weight while providing substantial cheek rest real estate—critical for shooters running thermal optics, night vision, or variable magnification scopes where eye position directly impacts target acquisition and target transitions.

This stock serves law enforcement patrol rifle teams, military-trained civilians, three-gun competitors, and precision rifle shooters who operate across multiple shooting platforms and need one stock solution. The eight-position adjustment range accommodates shooters from compact frames to larger builds, as well as equipment layering common in duty and training environments. The UBR Gen 2 represents the evolution of Magpul's original utility battle rifle concept—a proven platform that has seen extensive field use across professional and civilian markets.
