Product Description
Magpul UBR Utility Battle Rifle Collapsible Stock AR-15
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.

Durable and adaptable.
This is my second UBR stock. Love them both. One in Foliage Green and the latest in Stealth Grey. Constant cheek weld, adjustable to how much clothing your wearing and rugged as any stock out there. To top it off, it is a damn good-looking stock.

Its worth it
I hesitated before buying this stock based on the price over the CTR, which I already have on 3 of my AR's. Love 'em. But the Beowulf demands something beyond solid, and this is a SWEET stock. Rock solid. No play at all. Maybe a bit heavy on a carbine for some, but right at home on a range rifle. Perfect offset for a heavy barrel. It's worth the price. Surplus, as usual, has it for the best price by far. (Get the strike plate, too. It's gnarly. Ice that cake).

Perfect stock- unbeatable price!
If you want to get the best balance between a fixed stock and a collapsible- this is it. You also can't beat the service and price from Surplus Ammo & Arms!!
