The Magpul® UBR™ (Utility/Battle Rifle) Collapsible Buttstock is a fully-featured, adjustable butt stock 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 increases durability under severe impact conditions experienced during malfunctions clearing and accommodates large-bore AR calibers. The UBR&rtrade; also provides extra counterbalance weight to improve handling of full-length rifles and weapons with muzzle-heavy accessories or grenade launchers.
