The PTS UBR™ (Utility / Battle Rifle), 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 increase overall durability.
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.
This version of the PTS UBR™ is designed specifically for Version 2 AR15/M16 style AEGs. The rear of the buffer tube has a quick accessible compartment which can be unscrewed to accommodate various sizes of AEG batteries including many lithium polymer batteries designed for AEG buffer tubes
