...or try that new BCG in another rifle.
I put the old one back in and it cycled and shot just fine
Well I'm going to try the yellow coded buffer spring with the same buffer since its light maybe from it being under gassed itll let the bcg push back more letting it eject and cycle properly maybe even lock back after the last shotThere might be a clue in there somewhere.
Have you tried a lighter buffer spring?
The new bcg doent cycle it extracts but doesnt push back enough to cycle a load nor does it catch on the last round I've oiled the crap out of it and sometimes it double feeds and I have weighed themIf it cycles and locks back after last round with a mil spec bcg, it is not undergassed. The problem is the new bcg. Weigh the two and see if there is any difference in weight between them. Stop looking for problems with the rest of the rifle, it is fine. Start looking for problems with the new bcg, unless you want to keep throwing good money after bad.

How would it be over gassed? On 18" barrel and it has carbine gas system and it is a 3 .oz buffer with normal carbine spring. If you can please explain I would appreciate it. ThanksThank you, I was just going to post something similar, in fact, I'd put money on the barrel being overgassed, most are.
OP this post is spot on, but hey if you like rabbit holes there you go.

I'm sorry rifle gas system on carbine buffer
Yes I did use cheap ammo though, maybe I should get 77 grain also to try that I used 62 grain and still had same issue.I would hope so, when I read that I was, huh?
It all starts with gas port and too many manufacturers make them extra large to accommodate people using cheap, under-powered, crap ammo like PMC Bronze or Tula.

That's what I run is 55 and 62 grain55gr M193 or 62gr M855 or equal should run fine, you shouldn't need 77gr projectile to function properly.
My barrel is so short that all I ever seem to do is short stroke.
Running it wet is very helpful, but too much and you'll have a big mess on your hands!
A lot of time when mine is in the middle of a cycle she'll spit it out and won't let me feed any more in too.
Your not alone, bro. A lot of us have these same issues. A lot.
