First off the new upper is a LW RRA chrome lined from adco. Mid-length gas system, a2 receiver. Went to shoot today and with the sight centered it would shoot way left. I had to adjust it almost all the way right to get it to shoot center. The sight is literally almost maxed out towards the right. Is this normal? Seems odd to me.

The front sight might be crooked.  Give ADCO a call, the will get you fixed up.

Too bad you're not closer, I could fix it for you. Canted FSB is the most likely culprit.

I hate to bother Steve again but I guess I will have too. I had to swap upper once already because there was a noticeable chunk missing from the receiver. I will e-mail Steve again and see whats up. I expected it to be slightly off center but not like this.

I will wait and see what steve says. I am not sure if I got a completely different upper when I sent it back. He may have just installed a new upper receiver and I guess the indexing could be off. Hopefully I can get this taken care of ASAP.

Is this a common problem?

Common enough for me to make up graphics explaining barrel indexing.

Damnit...I can either send it back to Steve for a refund or into RRA for repairs. I'm sure that will take a very long time. I know everyone is swamped right now. I really like the upper and would hate to send it in but I may have too. I have some bad luck.
