Review Magpul Industries UBR Collapsible Rifle Stock, Fits AR-15/M-16 Pros

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.

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.

I had preordered the UBR Gen 2 stock first. Got tired of the wait and bought the Gen 1. I am not upset at all. The Gen 1 stock is super solid. Really easy to install too. I love the stock, it looks great and the cheek weld piece is really good too. There is literally no wiggle or slop in this stock. You won't be disappointed.

Perhaps one of the heaviest stocks out there, but that's because of the high metal content - which makes it rock-solid. If your rifle is front-heavy, this will help balance it out and you won't find a higher quality stock. It's worth the price.

This is the stock I have been waiting for! This thing went with my latest AR build just perfectly, if weight and price is not as important to your build as comfort and looks, this is the stock for you! Well built, zero rattle, beastly looks, I love this thing so much I built this whole rifle around this stock and was still able to keep the overall weight under 8Lbs 8oz with a bull barrel and optics. I will be buying more of these in the future, and Optics Planet will be the place I buy them from! Thanks for your time, and remember to use safe gun practices ALWAYS!

Super solid and easy to install. There is absolutely no wiggle or play with the stock. Rock solid product. This is the 2nd one that I have purchased. If you are on the fence when deciding to purchase this stock or another, just buy this stock because nothing else will really measure up in my opinion.

If weight is an issue, here's what I found. With the strike plate installed, the UBR weighs 26.1 ounces. The UBR replaced the basic Magpul stock on my Ruger 556. That basic Magpul was 14.4 oz. I replaced the stock carbine buffer & spring (4.9 oz) with a JP Enterprise Silent Capture Spring (7.2 oz). If weight doesn't bother you, both are an excellent upgrade, especially on my Ruger 556 which was front-heavy anyway.

Been looking at these stocks forever, just could t ever convince myself to pay the price. A little sale helped but know haveing used this stock, I wouldn't hesitate to pay full price. It's go some weight to it yes, which I don't mind at all, but that's what you get with a quality built solid stock. Will be buying another no questions asked!!!

This stock looks great and functions great. It fit on the gun snug without any movement. The looks of this stock is what sold this item. The stock slides into the different lengths with ease. It does weigh a little more than other stocks but when it was placed on my AR it balanced out the rifle out perfectly.

The stock was easy to install. It fit properly and locks up firmly. The pre-programed leanth stops don't work well for me, I removed the screw for future use. I use the rifle for high power service rifle competition and mid range. Having a consistent cheek wield is great and not having the edge of a conventional collapsable stock diving into my jaw is great. I no longer use a different lower for mid-range matches. The storage space allowed for a little lead shot to balance the rifle in off hand.

The Magpul UBR arrived well boxed and optics planet has the best price as usual. The stock is an excellent choice if your not worried about the weight. Thanks optics planet for the best prices & excellent service!!
