6.8 Feed Issues

[Brockles5211]

Guy I have now run about 150 rounds through my 6.8 (Red X Arms upper) and I am starting to have feed issues with the gun. After the 1st 100 rounds I thought perhaps the gun was dirty so I broke it down and cleaned it real good. Go out this weekend and start playing around with it again and after the 1st 20 rounds go through I start to get the same issue again. I wish I had taken a picture of exactly what it is doing. Best I can explain is it is feeding another round into the chamber without ejecting the spent round all of the way out. I am running 6.8 D&H mags with magpul 6.8 followers in them. Every mag seems to have the same issue. Is this feeding issue because of my mags or does this have something to do with my buffer tube and spring? Do I need to move up to a 7.62 buffer tube and spring? The current spring and tube are 223/5.56. All help is appreciated!!!

Keeping on eye on this....planning on ordering a RedX6.8 soon.

How does your BCG look? Extractor in good shape?

what ammo are you running?

itd seem that a lighter spring would make it easier to eject the round.

that was my thought, any way you can put a pick up of your spent brass?

BCG and extractor are both in good shape and good looking.

Sounds like a gas issue to me. Make sure your gas block is lined up over the gas port.

The spend brass does not look in bad shape the round that it is trying to load gets the brass all bent up just below where the neck is.

didnt you have issues the first time running this upper a couple weeks ago?

[Brockles5211]

That was the 1st time I had it out and put the 1st 100 round through her. She ran like a champ up until about the 80-90 shot mark and then started to jam up, but I thought that was because she was dirty.

It usually takes a lot more than 80-90 rounds for one to start having stoppage issues unless you are running it very dry or the gas system goes out of whack.

I ran (2) 100 round drums back to back through my Colt 6933 suppressed with no stoppages at all. This was with very dirty Tula ammo.

Sounds like a weak extractor spring to me which is letting go of the case too early, then trying to load the next round while the spent case is still in the chamber. I would also inspect the extractor again, all corners need to be SHARP, no burrs, no rounded edges/corners. If it checks out, replace the spring and try again.
