High quality, MIL spec lower by CLE with MAGPUL UBR buttstock .

The Magpul UBR (Utility / Battle Rifle), is a fully-featured, adjustable buttstock for the AR15/M4. Unlike typical

collapsing stocks, this modular design offers the stability of a fixed stock with consistent cheek weld in any


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.

Made in U.S.A.
