Didn't fitton the buffer tube. Started to thread on but started to strip the threads. Tried a different castle nut and it worked just fine. It did fit my wrench though.
<br>From PA: We're very sorry to hear that you had this issue. We'd be happy to replace this for you.

This is a very nice heavy duty castle nut with great finish. Fast delivery as usual too!

Fit and finish on this castle nut is excellent. Uniform Parkerizing, fit both a 3-point stock wrench and a mil-spec buffer tube from another manufacturer perfectly. Works as it should. Couldn't be happier!
