Fired off a few rounds the other day (semi) and noticed marks on my casings that I thought were unusual.
Is it normal for the ejector to leave marks like this?
What about scuff marks and scratches on the casings like this? -- The all pretty much have these exact marks on them.
Now for this one, I know this isnt normal. I have slight extractor nicks which I know could be a sign of over-gassing...
but after closer inspection, I found the cause which is a slight deformation on one side of my extractor.
What could possibly have caused this? Is it safe to just sand it down and just forget it ever happened or do I have gas issues?
Carbine in question is a 14.5 1/7 with feedramps Bushy sitting on a F/A lower, Colt BCG, H2 buffer -- Relatively new spring as it is a relatively new carbine. LEss than a hundred rounds though it. -- the above photos being the 61st to the 93rd rounds.
