So ran into another new issue yesterday at the range with my 308 build. It was double feeding. It started with, I could fire 2 and then as it was loading the third it would malfunction. Then it started happening more and more frequently until it was every single time I fired the rifle. This was a new malfunction and only has happened this range trip. The only thing I have done recently to the rifle was clean/lube the bcg and upper. Any suggestions on how to fix this would be awesome! Thank you!
