Description
The UBR GEN2 is an adjustable stock for the AR15/M4, designed to offer the same strength and stability as a fixed stock with a consistent and comfortable cheek weld in any position.
An update of the revolutionary Utility/Battle Rifle (UBR) stock, the UBR GEN2 features a fixed cheek piece to provide a consistent cheek weld in any of its 9 positions, and is compatible with Carbine as well as A5-length buffer systems. Designed to accommodate large bore AR calibers and withstand severe impacts, the UBR GEN2 is nearly five ounces lighter while retaining all the durability its predecessor was legendary for. Comes standard with front and rear QD sling attachment points, two footman’s loops, the ergonomic MOE SL™ angled-toe rubber butt-pad, and customizable storage compartment.
Made in U.S.A.

What hasn’t been said already? The ubr was an excellent stock and highly rated by all reputable professionals. Because of the success of the ubr, it became so scarce that most people begin marking up the price. Now we have a less expensive and improved option available. This is on the premium side of stocks but worth every penny. Superb quality and made right here in the states! If you’re looking for an adjustable stock that is stable and durable for maximum efficiency and dependability, this is the stock for you.

This is my first UBR stock. Normally I run Vltor EMods, LMT SOPMODs and lately Magpul SL-S stocks. I was always turned off by the price and the weight, both of which were a bit heavy. However, the UBR has shaved pounds and dollars, and I decided to take the UBR plunge. I bought the UBR 2.0 and initially installed it on one of my SBR’s. (12″ w/ LPV) That ran great, but it wasn’t “right”. I slapped the UBR on my DMR (308) and boy do I like it. The LoP is excellent on this stock. Perfect for using on a precision rifle. The weight has been cut down a bit from what I read, so that’s a benefit also. While it wasn’t difficult to install, it is definitely DIFFERENT, from any other stock install I’ve done. However, after installing it on my SBR, I found removing it and reinstalling it on my DMR (which was already running an A5 buffer system) I found to go pretty quick and easy. It has a very solid feel to it. I would probably like some foam taped to it to elevate cheek weld, but it is totally doable as-is. All in all, I’m very happy with my purchase. I’ve shopped at MSR Arms before in the past, and while, they still haven’t answered an email I sent 2 months ago (It was just a email complimenting them on their price of an item.) The entire purchase process is pretty straight forward, they have a nice selection of items. So all in all a good experience. I will very likely shop at MSR Arms again.

Shipping and billing was fast and informative. Customer service here is excellent. This isn’t my first time making a purchase from MSR and I can honestly say that the service, consistency and quality is top notch. The ubr gen 2 is obviously a great product at a great price but what impresses me the most is the quality of service MSR provides. I highly recommend using MSR for your firearm needs. Thanks again MSR!
