Board policy mandates I state that I shoot for BCM. I have also done work for 200 or so manufacturers within the firearm community. I am prior service, a full time LEO, firearm instructor, armorer, TL, martial arts instructor, and all around good guy.
I also shoot and write for various publications. Let me know if you know cool secrets or have toys worthy of an article...

If you read the rest of that post, you know that no grinding was needed this time. I ran degreaser and a shop towel through to get rid of the Aluma-Hyde, covered it with a Birchwood-Casey marker and reassembled. It works fine, now.
BTW, I do think the whole process I did today helped. I think there were still a few small metal filings in the channel from the grinding last night and that is why it still didn't feel quite right even though it was working by then. Flushing the channel with degreaser washed them away and now it is much smoother. Now that the black from the marker has dried, you can't tell anything ever happened. Phew!

BTW, let me be clear about something. I'm not blaming Rainier Arms for this issue. First, even though it seemed to me that it was the fault of the lower and not the bolt catch, I can't be sure which part was out of spec. Second, the people at Rainier Arms have always been great to deal with and fast to reply to emails so I will still buy from them in the future. Even if it was their lower that was the culprit, any company can let a bad item out the door occasionally. No company has a 100% QC record. Their track record from other items I've bought and all the posts I've seen of their products is very good.

When you say you are testing the bolt catch with a different upper, what exactly do you mean? It sounds to me like you're making a decision on whether it works or not by inserting an empty magazine and working the charging handle, is this correct?
If so, that tells you very little about whether it's working correctly or not. Your way of checking the catch allows a lot of time for the follower to engage the catch. With live ammo, it may be a different story.
I wouldn't touch anything else right now. I'd test it at the range. Then, whether it works or not, I'd order an LMT or Colt bolt catch and go from there. If the new one didn't fit, it would be likely that it was a receiver issue. But, that will be hard to tell now.

Yes.
As I've said, I will test it at the range, but I don't have a trigger group for it yet. Once I have the trigger, I'll do further testing. Unfortunately, financial restraints mean I won't have a trigger group for 1 -2 months.If so, that tells you very little about whether it's working correctly or not.
