AR wrench

[CKimbrow]

Tried taking the castle nut loose to install and single point sling adapter and broke my AR wrench! That nut is TIGHT! What is the best AR wrench to buy that will fit an M&P castle nut that someone could buy on a budget?

Thanks,

Calvin

I had the same issue. Get a new nut and go at the old one with a pipe wrench.

I got one off amazon for 8 bucks and worked like a charm. Mine was on tight but was able to get it.

Depending on what your budget is, you may want to take a look at the Hammer Head Rifle Tool. I have not used it myself but I have heard a lot of good things about it.
