I ordered a complete 5.56 upper
I ordered a complete 5.56 upper. The barrel seems Ok, but that is about it. The mil spec trigger group, I couldn't even drive the pins in on the bench. The holes didn't match up. I had another trigger group and put it in, perfect. I went to the range. The extractor doesn't extract, but, I had another bolt group. it worked perfectly. I haven't taken the bolt apart to see exactly where the problem is, but it jambs every round. I don't know where they are getting their parts, but they are junk. I have been doing builds for a long time. This is my first and last Thunder Tactical anything. In all fairness I have not contacted Thunder tactical to let the make it right because I don't want any more junk.
