I have a barrel nut that I am trying to loosen and it is being very stubborn. I have tried putting the barrel/upper in the freezer and tried getting some oil down into the threads, but nothing is working. I have already stripped a few teeth and am afraid to lose any more. Any suggestions?

I'm assuming you are clamping it and there are no problems that way.

The largest issue I've found when working on my various carbines is that the barrel nut and wrench tend to slip off each other. Having one person press down hard to keep the wrench locked into the teeth, and the second person using a cheater bar to max leverage, I've always been able to pop them off without trouble.


If you aren't using an extension off the basic barrel nut wrench for leverage, you are making things harder on yourself.

I recently had this issue with a Del-Ton upper - it even broke a barrel nut wrench. I used a Troy TRX barrel nut wrench, which engages about half the teeth on the nut, a 1/2" breaker bar, and two extensions. That finally worked.

Yes, I have it clamped in a vise with a receiver block. I am using a standard GI 3-Pin barrel nut wrench. I am pushing the wrench fully up against the nut. I guess I will have to try a cheater bar next.

I had a Bushmaster I had to use a propane torch on the nut.
I've got to get one of those PRI Barrel Nut Wrenches.
It does work with a standard G.I. barrel nut doesn't it?

If by "a standard G.I. barrel nut" you mean mil-spec, it does.

I read on another forum that it didn't fit a mil spec nut. Didn't make since. Just wanted to make sure it wasn't designed for a free float only.

I throw a socket wrench on, and have a jack handle that slides over it. I've not run into one that combo hasn't made short work of.

Torque wrench is not the tool to use for breaking torque. You need a breaker bar.

jackhandle? just a little bit of heat makes it an easy job with the right tool. 3 or 4 seconds in 3 or 4 places with a propane flame. thats all.

You are right, but it does work, and you need a torque wrench for reinstalling the barrel nut.

If you have already broken teeth without out a handle extension, and the wrench was kept flat (as you stated), you will probably just break more teeth, easier this time.
Your best bet is the PRI or other well made wrench that engages at least half of the teeth. But considering that you have broken some already, you will probably want to replace the nut.

Heat could do the trick, but don't get too generous with the torch. If that doesn't work, splitting the nut is the next step.

Carefully cutting thru the nut with a dremel or other grinding tool, and then retry the wrench. If you have cut enough of the nut, it will crack open and spread enough to come loose.

Remember, you do want to replace the nut now anyway. Also, accidentally making light cuts on the receiver threads won't ruin it

Just a thought but when dealing with some stubborn bolts or nuts. Try tightening,then loosen,,it works,sometimes.

I like the Oly combination wrench as it engages about 3/4 of the teeth of the barrel nut. DPMS and Smith makes a similar tool. I have messed up a few barrel nuts that were really tight using just the 3 prong GI tool.

The freezer trick worked for me. I left it in overnight (12+ hours) and then used a long pipe on the end of the wrench.

UPDATE:

I used the PRI Barrel Nut Wrench and a long breaker bar and was able to get the nut off. Thanks for all of the advice.

Does the PRI work better to overcome the spring in the Delta ring? I nearly broke 2 fingers when my armorers wrench slipped off the barrel nut.

Yes it does, I have had to tap it into place by going around the wrench head with a small ballpeen. Once you compress the delta ring spring it tends to stay compressed.

I had to tap mine on as well. It definitely held back the delta ring spring.

Many years ago working heavy construction I was trying to remove a large bolt with a 48" breaker bar. Then a pipe over the breaker bar and still it wouldn't budge. The boss came by to see what I was fighting with and laughed. He said to hit the breaker bar with a hammer. It worked.

I still do that with tight nuts and bolts. A good smack with a hammer on the barrel nut wrench will loosen a tight nut easier than pulling on it with a long bar.
