Well all the parts aren't quite here yet but I will start my thread with what i did to it.
Black Rain EC
Drilled hammer (went from .59 lbs to .42lbs)
Delrin Starfire upper bolt
Automag spring
Home-made rear cocking knob
Double trigger shoe.
it already had a different valve, the port on the valve is bugger than the largest port on the stock valve but I don't remember exactly what brand valve it is, may have been a magnum valve...not really sure.
Plus I made the feedblock sleeve so that I can have a regular elbow on it. plus the bottom line (but that is part of the Black rain) the only other thing I was thinking of doing was the trigger job that is on the VM Empire site, but other than that that is pretty much it. Oh yeah and I ordered a plate to cover the original cocking knob channel and it will be engraved with VM-68 SS. lol once I get all the parts and get it together I will post some pics.
Oh and in case anyone cares the serial number on my PMI 3 is 000686 with the orginal factory aluminum side plates on the trigger assembly, so this is an old gun. But I am keeping all the parts so that I can return it to stock condition if I want. Well let me know what you think
