thank you fossilhead, i checked your link and didnt find the information i needed however.
i believe it was origionally a pmi.
all i really need to know is how to put together the lower tube. The valve side is ok, its everything behind the regulator im sketchy on. I have bunch of pieces, im left with. a spring, two silver pieces, a large cylinder, a smaller cylinder and, a tiny brass piece resembling a cupseal etc.
if anybody could give me a diagram or picture of the order these parts assemble, or just tell me step by step how you assemble this part of the gun.
thanks in advance
