I have never purchased a gun before. Looking into buying a used one with supposedly about 2000 rounds or so. A major reason Im looking into it is because it is close enough to FTF. The gun looks good with pretty minimal wear, except the extractor appears to be a copper color. Looks like the black coloring on it burned/wore off. Has night sights, and 10lb spring. V1, but was converted to lefty safety. He is including all the original stuff, box and everything with two mags. I guess what Im trying to figure out is a fair price for it. I dont have a idea of what these go for. From what Ive seen its roughly $750 new. He wants $525.
