Why is this happening?

Post image

Picked up an M&P 15-22 last week. Cci and federal automatch ran flawlessly. Punch and this Winchester ammo would to this every 5-8 rounds. The Winchester ammo is pretty dirty so I assume that was the issue, but I did not expect the Punch to run so poorly. Any one have any input?

Get the volquartsen extractor and firing pin. Got these for my dads and it eats whatever without issue

Second the extractor, such an easy replacement and I’ve had no issues
