I have some 6.8 magazines from PRI and AR Stoner. One manufactures feeds well. One fails to feed on occasion. Which one do you think hangs up, specifically hangs the case on the leading edge of the magazine?
Mag 1 is from PRI
Mag 2 is from AR Stoner
Side by side, the bright circles are the rim of the cases reflecting the camera flash.
In my Daniel Defense the Stoner is less then optimal. Nothing a Dremel can't fix...
