Customer Ratings & Reviews
AR10 barrel nut wrench WORKS GREAT!
This ar10 barrel nut wrench works great. It goes on a little snug. Just a light tapping with a mallet worked well for me. I liked the fact that it went on snug as then the tool would stay put while my hands were off of it. I used a torque wrench to tighten the barrel nut, and I had no fear of slipping or breaking. This thing is WRENCH! It is made of real steel. The reverse side fit my floating hand guard nut as well.
AR10 barrel nut wrench works really well.
Perfect fit for my AR10. If you purchase this, you need not buy the free float nut wrench from Armalite. I recommend this PRI part.
AR-10 barrel nut torque
I installed an Armalite free float tube on my AR-10A with this wrench, and it worked as advertised. Very well built for the price. Some reviews are a little miss leading; this will work with a stock barrel nut on the AR-10. Pictured is the wrench fit up to a standard barrel nut I took off the rifle. So no need to buy two wrenches to replace an Armalite barrel nut.
I would recommend this 308 barrel nut wrench
ar10 barrel nut wrench tool fit excellent and secure for final torque
ar 10 barrel nut wrench
Used this on my Smith & Wesson MP10. Worked perfect.
Great 308 barrel nut wrench
Fits my 20 holes free float barrel nut snug. I like the heavy-duty construction and the five extra long pins. The right tool for the right job. Nothing like some of the cheap combination tools.
Best AR10 barrel nut wrench
Perfect fit for my Smith and Wesson M&P 10 stock barrel nut
At 10 at lite barrel but wrench
Says for ar10 but only fits one kind of barrel nut system so make sure you verify that I contacted company about it being 1/16 off from lining up with my ar10 Smith and Wesson 308 and they told me it’s not for that so sucks they did offer to exchange it but I had already made this one work which voids it but it’s not a universal wrench be ware

Haven't used it yet still waiting on parts for my build, but this thing is built like a tank! I do not believe there will be any issues with it, looks very well built!
