170 isn’t TO bad if your not a C&R holder, figure 120 for good, 20 for shipping 20-30 for transfer. Bonus of buying local is that if there is a problem you can HOPEFULLY trade it for another, and you also get to pick them out from a pile for the best. I had purchased a Chinese for 170, but its gas-piston was screwed up and it wasn’t feeding right. I went back and asked them to help me fix it (piston could not be removed). We looked at it for about 15mins, then they said I could just have another. They really didn’t let me pick one out that time, but gave me a great condition "Chinese Paratrooper" that was marked at 230. The guy said I shouldn't have much problem, it had a 30rd mag (correct the feed problem) and a bright new bore. Haven’t fired it yet (tomorrow I will though) but it is VERY nice.
I try to support locals as best I can, but sometimes I just can't, like when their asking 300 for a K-31.. I'll pass.
