I have a Gen 2 5.56 . Few hundred rounds through her at this point. I was having some feed issues in the beginning. Turned out to be a certain magpul mag . Took it out of service. Had little dents from bullets points hitting it . Top round. This happened just a few times till I figured out it was the mag. I ain’t got a clue why on the mag either. Any higher round folks out there. Just curious how y’all’s has been. Wardawg Attached File
