I have a AK from Arsanal in TX I think is great but it does something odd. When the empty cases come out they are all cripped at the case mouth. It is about one quarter of the diameter creased in tword the center. I have had a couple of failures to feed in about 500 rounds. Any thoughtsThanks

Welcome pmbss396

I'd venture to guess that the crimping is being done by the case hitting some part of the weapon after extraction.  Perhaps the bolt handle, carrier face, or dust cover? ETA: look for any indication of case impact on those areas...

wrap a little foam padding around your ejection port...tape it in place temporarily if need be.

i'll bet your spent cases come out looking better or untouched.

a little more oil, a little more grease and a slit radiusing of the feed ramp and chamber mouth will cure the ftf's. if unsure of how to perform the ramp/chamber radius polish, let a smith do it.

good luck and welcome to the dark side!
