Magpul Gen 2 UBR Stock Black
The Magpul UBR (Utility / Battle Rifle), is a fully-featured, adjustable buttstock for the AR15/M4. Unlike typical collapsing stocks, this modular design offers the stability of a fixed stock with consistent cheek weld in any position.
Seven-position length-of-pull (LOP) adjustment is quickly executed with gross motor movement while the integral preset system allows direct access to a preferred position. A robust lock mechanism and multi-shell construction increase durability under severe impact conditions experienced during malfunction clearing and accommodates large-bore AR calibers with ease. The UBR also provides extra counterbalance weight to improve handling on full-length rifles and weapons with muzzle-heavy accessories or bull-barrels. Optional components such as dual-side sling mounts and metal strike plate allow the UBR to adapt to the mission at hand.
