I took measurements before I sent it.Please show good close up and in focus pictures of Mr. Straits workmanship. I am interested in his technique. Did he say he could use your existing barrel?
You may want to photograph and record your USGI bolt's lug dimensions and your receiver bolt lug recesses before shipping your rifle off for the conversion.
He will use the existing barrel and says a GI barrel will fit if I choose later without modifications.
I guess he cuts the Chinese receiver lugs and spot hardens with Kasenit or similiar
