Is dented brass a buffer weight issue?

[Posumkiker]

I just completed my 308 AR build. Head spacing is correct. After test firing, I noticed that the brass had a small dent near the shoulder. Everything functions properly. I was thinking that the brass was being ejected so forcefully that it was being dented on the deflector? Could this be a buffer weight issue?

You have a picture of the brass?

Not with me. I'll post one tonight. It is pretty small up near the shoulder.

It could be an overgassing issue, and a heavier buffer would help, but we need pics.

All that high end stuff and no adjustable gas block?

A heavy buffer may be better suited to solve this, especially if he isn't reloading his own ammo.

Here is my brass in 2 different lights. Thoughts?

Extractor marks on the rims?  Check the relation/location of those dents, compared to the location of some extractor marks.  See if both round have marks in the same locations.

That's how steel cases look out of the AK, from the cocking handle SLAMMING into them.

 

Before they get launched into the next county.

I installed a Seekins adjustable gas block and an XH Buffer from heavybuffer.com. That did the trick. Thanks for all of the input!
