I'm looking for a durable jam nut wrench. I had a MI wrench and the tooth broke. Anyone know of one that won't break?

You want a wrench for the standard barrel nut or for some free float tube?

If standard, the cast DPMS and other cast AR15 wrenches engage all of the teeth on the barrel nut and will not break.

If it's the buffer tube castle nut that broke your wrench, I think there are purpose built wrenches for that.

This is what I used. The one tooth broke off within a couple of times of removing my jam nut on my free float rail.
