Excellent

I destroyed a barrel nut with one of the “fancy” expensive gunsmith tools. I took a risk and ordered this one and I can say that it was excellent. It fit snug and you can use it with a torque wrench.
I’m extremely happy with the purchase. Three times cheaper than other multi-purpose gunsmith wrenches but of exceptional quality!
If you need an AR15/DPMS style LR308 barrel nut wrench this is the one!!! Highly recommended!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Great for DPMS 308 barrel nut

Great for my 308 DPMS build and did not break the bank or drive me crazy like many other cheap and useless AR style tools out there

It wont chop wood for you or store silly survival string inside the handle however you can open a beer with it after you are able to confidently loosen and tighten a 308 barrel nut without marring it up and it likely works for AR 15 nuts as well

Geissele Barrel Nut Wrench

An obvious need if you’re going to install a Geissele rail. Unfortunately when I wanted to get mine it was either out of stock or the seller couldn’t ship to Puerto Rico. But not AT3, they came trough and with a great customer service.

Thanks for sharing your feedback, Jonathan. We're glad you're satisfied with your purchase. Cheers!
