overgassed AR (lemmy.world)

So, if I have an overgassed AR, and am kinda an idjit, what's the best way to make it gooder?

A heavier spring? Do I need to mess with the gas block or get a different tube? Am I going to have to do all this multiple times to get it right, or is there a suggestion or guide or something?

Ideally it should be ejecting from 2-4 o'clock.

I would try using a heavier buffer first. A lot easier to swap that than the gas block.

It should be mentioned that being overgassed isn't...the end of the world? It'll put slightly more wear on your rifle and you'll have more felt recoil, but it will also work more reliably. Basically every AK is "overgassed" in this sense except the ones hobbyists screw with.

That makes sense. It doesn't really have much felt recoil to be honest. I mean compared to other rifles I've shot. It does shoot gas at my face, but that may just be the platform as well.

I'll try a buffer, they are a bit cheaper. That's just the weight thing that hangs out on the spring, correct?

Yes, that's the buffer.

Where are you getting gas in the face from?

Also, how long is your barrel, and how long is your gas tube? Ideally you'd have full rifle length for both (16" barrel, 12" gas tube) but you can have a short tube on a long barrel. No idea why, but they exist.

I guess it's more of a cloud around the bolt. I know the barrel is 16 and 12 sounds about right for the gas tube.

I got a kearms cdr, so I think it's pretty basic, probably milspec everything. I'm going to have to weigh the buffer and see what it is.

You make a good point about reliability though, and it's never not done a thing it should (load a new round and discard the old one)
