I  went through this was psa.
Probably an undersized gas port or rough chamber causing issues.
Buffer isn’t gonna help with that

Well crap, guess I’ll have extra buffers laying around, already ordered it.  The gun guy said it was ejecting too fast, but not knowing these types of guns at all I went with his idea.  With my standard buffer, it was ejecting but smashing the new round in half.

Yeah, H2 not ejecting is showing not enough gas or too heavy buffer! But carbine buffer was showing too much gas or not enough buffer. Maybe we misinterpreted your first issue as too much gas and cycling too fast as not enough gas. Maybe without the gas it wasn't clearing all that yellow junk out and the tips were getting smashed cause it wasn't cycling back quite enough.

You do have a weird, non standard issue though unfortunately. Cans usually are adding more gas and pressure so you need to up your cycling weights.

I wasn't right with my first assessment. But I do agree that a H3 wouldn't help if H2 didn't help. It would fix the crushing cause I think a H3 would put it to a single shot!

I'm also leaning toward a gas issue. It shouldn't be that hard to fix issues with subs and a can, the fact that is has for you means something more involved or harder to fix is going on.

Great, I should have mentioned the last time I shot it, I took the can off.  Maybe my next step should be an adjustable gas block?  And the next after that….throw it in the ocean!!

I've read this thread a few times to make sure i had not missed anything before commenting again.

It's appears to me that you have not determined what some of the parts are that you are working with. We don't know what buffer weight or buffer spring you started with. Those are some key components that need be known before throwing money at the problem.

Have you determined if the gas block you have is correctly installed?  If the gas block is not installed correctly, you could be experiencing a reduction in gas flow.

This is far fetched...do you have the correct gas tube installed?

I saw it mentioned and it's worth checking the gas port on the barrel and see if it's in spec. It's also worth checking that your chamber is in spec as previously mentioned.

If you have all standard carbine spec parts and all parts are in spec, then your firearm is most likely not compatible with those Hornady Sub X rounds

Because of laws, well, the upper was purchased complete and I’m not sure what exactly each part is.  I’ll tear it down and see if I can get better info.   It was supposed to be all aero precision, but it isn’t stamped on the barrel anywhere.

Took the current gas block off and ordered an adjustable one off midway.  Had drill the old one out cause one set screw was so tight and stripped.

Throw it in the ocean and buy an AK. Problem solved.
