The Magpul UBR (Utility / Battle Rifle), is a fully-featured, adjustable buttstock for the AR15/M16. 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.
Counterfeit UBR rifle stocks are available on online auction sites, local gun shows and even at some local retailers. Buy from authorized Magpul dealers to ensure that you receive an authentic Magpul product.
