MAG-330UBR: Magpul Ind. UBR 7 Position AR15 Stock & Buffer Tube Housing
The Magpul UBR (Utility / Battle Rifle) AR15/M4/M16 Stock, 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 Magpul UBR also provides extra counterbalance weight to improve handling on full-length rifles and weapons with muzzle-heavy accessories or bull-barrels.

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. (ie. SLASH Buffer)
