The Magpul UBR (Utility / Battle Rifle), U.S. Patent 6651371, is a fully-featured, adjustable buttstock 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.

Features:

  • Mounts on durable Entry-Length Receiver Extension tube (included) to accommodate the common M4 carbine buffer and spring
  • 7-Position LOP adjustability with customizable preset system for fast access to preferred length
  • Adjustment lever requires only gross motor movement to operate yet the entire stock remains streamlined and anti-snag
  • Solid "fixed stock" lockup and consistent cheek weld in all positions
  • Enhanced lock mechanism w/ internal impact buffer increases drop strength and shock resistance
  • Multi-shell construction provides solid foundation and shields critical operating parts from penetration damage
  • Sloping cheek weld combines a slim profile with user comfort
  • Stout construction provides counterbalance weight for improved weapon balance and handling
  • Storage compartment in tail of stock is removable and the door is reversible for user preference
  • Removable 0.30" Rubber Butt-Pad offers an anti-slip surface and increased impact protection
  • Front/Rear Reversible QD swivel sling mounts fit up to 1.5" push-button swivels (swivel not included)
  • Bottom 1.25" sling loop
Color: Black
Compatibility: For M4 Series Airsoft and Real Steel Rifles

"I got this a few weeks ago, It's amazing, very high grade hard plastic and adjustable for many types of players. The only thing is it seems magpul items are a little tough to put on my gun. However my gun has pretty thick rails and i always get it on. Now have my gun is magpul based on the outside. Feels nice, way lighter than it use to be.

"THIS IS AN AMAZING STOCK. it gives you the "best of both worlds" as far as stocks go. it is adjustable to i believe 6 or 7 positions (never bothered to count, though i prefer position 3) extremely solid when locked, there is absolutely no movement/wobble. iy does have space for a small stick type li-po battery, i don't have a gun wired to the rear but the option is there. i have this installed on my KWA KM4-S i did have to modify it. (i'm not sure what to call it, but,) the part that extends out of the back of the lower receiver, the tube-ish part that the buffer tube slides onto. you have to cut it down to an inch long. 1 inch from the flat part of the back of the lower receiver to the tip of the tube-ish exstention. this stock doesn't use a buffer tube (like a fixed stock) but this stock is built in two parts, it has an upper and lower portion. the top part has the cheek weld, and the niches for the lower part to slide on and lock into. and the lower part has the butt-pad adjustment trigger and a little storage compartment (great for holding batteries or a winding tool if ur high-cap mags use them. you can take off the to parts that make the compartment simply by unscrewing the 4 screws that hold it in place. and MagPul was kind enough to include shorter screws than the ones that hold on the plates that make up the compartment so that they keep debris from getting into the screw threads. i have done this and it makes adjusting the stock a lot easier because the shape of the stock makes it a bit awkward to get a good grip to pull the adjustment trigger.

all-in-all, i have no complaints about this stock. i think it's build quality is amazing, it's integrity and reliability is amazing, i've had no problems with the adjustment trigger or the lower section of the stock getting stuck/jammed. it's pricy, yes, but you are buying a MagPul product... they aren't cheap anyways. very ingenuitive design, amazing quality. highly recommended for any player type, assault, sniper, CQC/CQB (though it a bit big and heavy, so if you're using it for CQC/CQB it might be a bit awkward at first but i'm sure you'll get use d to having it) but if you're looking for a happy medium between a full stock and retractable stock and have the budget. Get This. you won't regret it. i've had this on my KWA for almost a year and love it more than the crane stock on my other gun an Aftermath "Knight" (don't really use it, but it's a fun gun to run around with cuz it's light weight)
