MAGPUL UBR

MAGPUL UBR(Utility battel rifle) Collapsable Rifle Stock for AR15⁄ M16 and 7.62 x 51 AR'S The Magpul UBR (Utility ⁄ Battle Rifle), U.S. Patent 6651371, 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 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. NOTE: The UBR includes the necessary Entry-Length Receiver Extension tube and all mounting hardware. An M4 carbine buffer and spring are required for use with the UBR and are not included. 7.62x51 ARs may require the use of a custom short buffer and spring.
