What are signs of AR15's being over gassed

[toolsofthetrade]

What are the signs an AR15 is over gassed?
TIA.

Brass gets thrown about twice as far as a well regulated gun and you might see ejecter pin marks on the headstamp of fired brass.

Does an overgassed setup affect accuracy...?

It really shouldn't for all intent and purposes unless it's such a violent extraction/ejection that it causes some bbl movement. I'd think that would only be in extreme cases. It's not conducive to long brass life.

Remember when we say throwing the brass far that 8 feet is not far, 15 is.

My long range Grendel throws brass about 8 feet, my carbine about 5.

It does not matter.

Bob Reynolds of Templar just sold a great AR10 type that throws the brass 2 feet max

That rifle was 1/2 moa in the first ten rounds after a quick zero
