I posted this problem on another site, and so far haven't gotten much help. Probably because it sounds so screwy that noone has any idea of what to even suggest. So, I thought I'd post here hoping that someone might have ideas on how to fix this problem or suggest a course of action.

Now I'm not one to come running to this forum with the slightest problem, but as I said I am at a loss and I need help, and I'm getting frustrated.
I bought a new 14.5" stripped upper, carbine gas system. I won't identify the company yet, but it is considered by most a top tier company, and I'm not sure if the upper is at fault.
Bottom line is that the gas key (on the carrier) gets "clogged" after firing just one round. With the key clogged that leads to a variety of problems, you name it I've experienced it. I've swapped out every part, and the problems change, but it still will not run reliably. Bottom line if gas isn't getting inside the carrier the rifle won't run, simple as that.
Today, I went to the indoor range to test, thinking I had found the problem when I discovered the gas key "clogged" and cleaned it out. Nope, first round and it clogged again.
So I swapped the bolt carrier group, and that one clogged up too. It is carbon clogging it I think, because CLP in the key disolves it in a matter of seconds.
I've tried PMC Bronze and XM193, same problem.
The first bolt that clogged is a chrome bolt that has been lightly used in another rifle, and it never failed. The second bolt I tested today was brand new, first rounds ever fired through it.
I'm at a loss! All I can think to say is HOW! and WHY!
Any and all thoughts appreciated.
