I have over $450 in to this setup but have only put a few hundred rounds through it. I lost interest in the conversion so it's just been sitting in my safe. The upper still has the gas system and still looks almost new. I bought the conversion kit from Bushmaster a little while ago along with a 30rd clip. Also includes a charging handle. I can email pics on request or I can post some if I find a place to host. Looking for a Cetme, G3 variant. Can add some cash if need be.
