I should’ve gotten a picture of the malfunction, if I remember correctly I did have a live round in the chamber, a stovepipe, and almost a double feed all at the same time. I was using pmags for the record.
I’ll start with a H2 buffer before I mess with the bcg parts.

That sounds like what I get when I have weak ammo. Looks like a double feed with a live round and spent casing. I assumed what was happening was that the ammo wasn’t strong enough to get the bolt far enough back for the casing to clear the ejection port. That was when I had an H2 in the gun and shooting weaker ammo. I’ve had the H in there since. Still have the other buffers in my rifle bag, but prob haven’t touched it in years.

Sounds like a good plan. Eliminate variables one by one.

Yeah I don’t suppose there are A2 front sight/gas blocks that are adjustable. I wouldn’t want to mess with another A2 sight anyway because it was a pain in the ass getting it onto the barrel.
I can always punch out the pin in the h2 buffer and switch out one of the tungesten weights for a steel buffer weight I have lying around and turn it into a H buffer from there.

Now that i think about it I did have a Ar out today that had a h2 buffer, could’ve swapped the lowers and see if it fixed the issue. Damn.

Quick update:
Ordered and installed a H2 buffer and no malfunctions, but it's still overgassed ejecting at around 2:00, rather than around 1:00 in my previous range trip.
Perhaps a H3 will do?

Zero on the gooseneck still holding, highly doubt it'll retain zero if I remove it and reinstall.

I would say as long as it’s funcitoning well on your selected and range of ammo, all good. I wouldn’t worry about the 2 o’clock ejection. Many of my guns will do that with the full pressure 5.56 ammo. Some will eject to the 3-4:30 position as well.

If you’re really set on “tuning” the ejection pattern, another option to try are Springco springs. Prob cheaper than the heavier buffers.

I'll get working on those springs at some point. Quite busy with college finals coming up. But it seems that the malfunctions have been mostly solved with the heavier buffer, I say "mostly" because I only put a mags worth of ammo downrange today in that particular franken-AR (It used to stovepipe once or a few times per mag in my first outing)
