I have an AR-15 with a rifle length YHM forearm that I bought a few years ago and want to change it to a midlenght forearm. Do I need a YHM wrench to loosen the jam nut or can I use an AR-15 wrench? Anyone with info that can help me with this project will be greatly appreciated!
an armorers wrench doesn't have the spanner part for the jam nut. Yhms wrench or possibly a taped off screwdriver and hammer. You may be able to find a spanner wrench a little less expensively than yhms wrench or a strap wrench might get you by.
That's what I was afraid of, n I don't have aYHM wrench. I was thinking bout the screw/hammer thing but didn't want to damage the nut, but I never thought of taping it. That is a great idea! Thank you so much!

A leather belt and some channel lock pliers will do to remove the YHM jam nut,as long as a gorilla didn't install it.
Screwdriver and hammer works for me. You would really have to hit it badly to mess it up.
Tks for all the helpful info. It is really appreciated!!
I have an MI rail with a similar jam nut and I always just use a screwdriver and hammer, no tape and have never messed the finish up and I've taken it off and put it on more than a couple times
