Solid stock
by Daniel -
After a year of use this stock is still as tight as it was new. Installed on a 16" heavy barrel AR15 build. It is a bit heavy but I think that it balances very well especially with a bi-pod installed on the front. Appreciate the multiple QD mounts for different sling configurations. Only ask would be a M-LOK or short pic rail on the bottom to mount a rear mono-pod because bags are a pain to lug to the range.
Best collapsible stock on the market
by Harold
The UBR is easily the most solid, best-engineered collapsible stock on the market. No movement whatsoever. No pulling beard hairs. A5 buffer compatible. The only downside is it is a little hefty, but not overly so. If you are trying to build a lightweight rifle, this is not for you. And balances best with an 18 or 20 inch barrel. Still, it’s one of my favorite stocks
Right price

I like how tight it locks after u adjust the stick length little to no wiggle. Light weight and quick to adjust

They are heavier than lot of stocks, but I like the weight especially when running on SBR with suppressors.
Love it- great stock
by William
A little heavy but extremely comfortable and reliable. Run this on my .308 MSR that I use when I shoot 3-gun “heavy” division.
UBR 2.0 Not Indestructible
by xxxxxxxxx -
Buffer tube bent when rifle fell off a counter. Thought these would be resilient to that sort of damage but was wrong. My fault really but a little disappointed for such a small fall. Magpul support didn't feel it was a quality issue either.
Primary Arms shipping was fast as usual.
Great for the money.

The UBR has always been my favorite stock as far as looks and functionality. Feels solid. Only issue is weight. Noticable heavier than the Magpul CTR I previously had on my rifle.
