Alright, so a guy on NTA (wont mention his name right now) posted a WTT ad for a threaded buffer tube. He was willing to trade his Magpul AFG for it. So I contacted him and told him that I had a spare tube and CM LE stock left over from a King Arms Crane stock that I bought for another guy. He wanted to put the tube on a 1911 carbine kit from Evike. He said he called them and asked if it would fit, and they said yes. So we agreed to meet, and I even bought 3 MAG mids= magpuls from him. A few days later, he told me that the tube didnt fit his kit. That was November 30th. I got a text from him this morning saying that he wants to trade back the AFG for the tube. Me being the nice guy that I am, ALMOST feel like I should. So should I? Or should I not?
