Great wrench...solid tool!

Just installed a free float handguard on my BCM. Used this tool to break the old barrel nut free and torque the new one. It worked great! I had to use a mini sledge and three hits to bust the old nut free...no problem. Torqued the new one to approx 50 foot pounds (to line up gas tube hole). Performed flawlessly. Worked well on the flash hider as well.

Works Great

I put 70 foot pounds of torque on this when tightening a barrel nut and it performed great. Heavy tool that works exactly how it is supposed to.

Just what is needed at the right price

Nothing fancy, it gets the job done.

May require modification

Just like two other reviewers, I purchased this tool to install an Aero Precision BAR barrel nut. The pin pattern diameter of the tool was too large for this application, and I had to do a good bit of filing on all three pins to remove enough material for it to match the hole pattern in the nut. With modification, it fit perfectly and remained sufficiently robust to apply 60 ft-lbs of torque to the barrel nut. There aren't many choices out there for installing a BAR nut, but this tool works fine if you have the patience to make it fit.

excellent for most small nut application

this wrench works great with standard barrel nuts. The interior dimensions do not allow its use to install the JP enterprises barrel nut on the jphg-1d, however, due to smaller radius of the space designed to fit around barrel. I had to buy the DPMS model to use with this handguard's barrel nut. Still, I use it and abuse it in every other application and it is strong and easy to use. It is the strength of the design that makes the inside radius small.

Does the job

Remember that this a reproduction of a military/factory wrench. I think this item is getting a bad rap since the reviews are for applications that are not using mil-spec or factory add ons. It definitely gets the job done with the mil-spec parts.

Might need adjusting

Solid and nice construction. The three posts for the barrel nut are strong and well built... but would not fit into a BAR barrel nut by Areo Precision. The posts were .02" too wide. After clamping it into my vise and a little work with a dremel tool it works fine. I don't think the little amount taken off will effect the integrity of the tool. Overall it is a nice tool worth the money.

Will NOT fit Bull Barrels

In case you are new to the AR platform or new to working on them, as I was, you need to know that this wrench will not fit bull barrels to wrench the barrel nut. The lugs are in the right spot, but the cut-out is not bug enough to go around the width of the barrel itself. Since this is the reason I bought the wrench, I can't offer an evaluation on the rest of it. I know there are other combination wrenchs that will work, so I'd have to recommend something else.

Would not buy again

This thing looks rock solid, but in my opinion the pins are too short to ever turn a barrel nut, especially an aftermarket one. If you are installing a Larue freefloat rail, DO NOT BUY. The threaded ring gets in the way and this wrench will just damage the barrel nut.

Don't waste your money.

One of three pins snapped with little pressure applied making tool useless for barrel removal. Poor quality steel.Might have been made in China. UNfortunately I had it for a few months before my first use, so can't return it. Surprised at lack of quality for a Brownells product, but it is becoming more problematic these days with Brownells.
