Ok I’ve looked at my bolt and tried finding definite answers so here’s my question.
I have a TBT HK USC to UMP 45 acp conversion from Tommy and I just bought a 40 cal bolt barrel spring and mags.
So will the parts kit bolt 40 cal drop into my UMP or will I have to send the bolt off to be milled down? Will the bolt I’m getting not look like this?
I am getting swap parts tomorrow so kinda curious today about tomorrow. I really hope my receiver is already been fixed to accept the 40 cal bolt?
Thanks
