So, sadly the feeding issues have come up again on my 7.62 CSA. The rounds aren't feeding right about 30 - 50% of the time, depending on how many are loaded in the XCR mags. The rounds aren't feeding at a high enough angle and so the tips just hit the receiver wall just in front of the ramp/barrel. I'm a bit hesitant to snap off the adapter's feed lips as id64 did, but I'm not sure what else to do...
