I had some issues viewing the last page of the thread- and this thread is very germane to my interests.
I just got a full rail Springfield Operator back from Innovative Custom Guns/Jim Milks. It got completely gutted and rebuilt with EGW parts and a Kart bushing barrel, along with the Nighthawk IOS plate system. It's a "lowered" firing pin stop, and I asked for it to be sprung for 230 grain factory ball. I was told to use Wilson or McCormick magazines. I'd love to post pics/dimensions, but are there any particular ones that would be of most interest to the thread?
