Sadly, the lower is indeed Olympic Arms.

I still wouldn't give up on the rifle. A lot of people shoot Olympic and they run well, they just tend to be a bit more finicky out of the box. There's a guy in my gun club that shoots an AR in NRA Hi-power competition that's an Olympic. I've got a close friend that's got a full size rifle running on an Olympic lower and it shoots just fine. My experience is that Olympic isn't bad per se, but they are a bit more finicky than other lowers.

Also, I think the problems with your bolt not wanting to cycle probably has more to do with the upper than the lower. This is a dumb question, but I do need to ask it: you have cleaned and lubricated the bolt carrier, I assume?

I would pose a question in the forum at AR15.com. Those guys are geniuses, and they'll likely have an idea what you should try to do.

I shouldn’t assume you know all of the lingo of ARFcom etc.

When I say “wet” I mean well lubricated. Also, most likely the lower is not the problem.

I quit counting at 250,000 rounds through Olympics. I cannot recall any major problems with any of them. BTW IBMG have you called Olympic and talked to them?
