My question is specifically in regards to the ejector on the bolt face.

A brief rundown as I see it is the round gets stripped from the mag by the bolt. When it goes into battery the extractor slips over the case rim. The ejector is compressed until firing. The extractor holds the case rim to allow the spent case to be pulled from the chamber. The ejector is opposite of the extractor so as soon as the case is free from the chamber it helps flip the spent case out of the ejection port.

My question is how much does the ejector influence the ejection pattern of the rifle?

On my 6 ARC I have been playing with it a bit, but seems like no matter what the ejection pattern is the same.

I sent another suppressor to get upgraded baffles and upon getting it back I had to open the gas block up 2 clicks to get lock back. Now it has way less back pressure.

Also because the rifle seems to be over gassed I've tried numerous different buffers (at least 3 of increasing weight). The heaviest one is 5.8oz. I've also tried different buffer springs as well.

The thing is, as I worked my way up in those weights and springs, I could almost put a 5 gallon bucket out there at about 5:00 and caught all the brass regardless of how heavy the buffer is.

It's not really a problem per se, but I'm thinking that I might be missing something. I could definitely be slowing down the carrier itself with those heavier buffers, but the ejector spring might be extra strong. At least in theory a really strong ejector spring might cause the ejection pattern to not really respond to carrier speed changes.

In the past as everything got slowed down the ejection pattern would move and respond accordingly. This one though is a bit strange. The bolt is a Type II Grendel bolt from RCA in a Griffin BCG shooting 6 ARC.

So am I just nuts or does it sound plausible? If it's a thing to have extra strong ejector springs is it possible that has that much influence on the pattern?

It's not causing malfunctions but I am trying to fine tune everything so depending on what else I can come up with it will help me figure out the best solution.
