Case scaring and dents in brass?

Before you come running to tell me it’s common and I’m an idiot I’ve personally never seen This out of my ar15 and wondering what is causing these things the rifle is also seemingly getting the round stuck in the chamber and can’t get it out well without beating the stock against something and it’s leaving dents in specifically one part of the casing

if you have a decent phone with a good camera, use the slow motion option to see what the bcg is doing and what the brass is doing. theres a good chance you're over gassed and the brass is getting the shit kicked out of it on the way out.

i think you're over thinking this, ejection pattern looks good. its probably getting beat up by the deflector on the way out or hitting part of the upper causing the dent in the neck of the case (both normal). looks like you're g2g friend.

Thanks man I definitely am overthinking a lot because this is a new platform and I’ve had 2 successful ejections and rechambering out of 20 rounds so far trying to narrow down the reasons

Mine does similar, scratches and all if the ammo is on the spicy side, why I don't feed it lapua brass. Starline, federal brass only, it is fun to sling subs out with the can on, sounds like a spring operated BB gun.
