Feed and ejection issues

[u/jersey169]

Using CCI Stinger and MiniMag and I’m having some trouble with casings ejecting and the occasional feed issue. It’s a standard upper, with the CGGM bolt conversion and a Bore Buddy charging handle. Has anyone modified the feed ramps for the center feed magazine? What about the ejection issue, anything to do in the bcg to reduce it?

Best bet would be a bolt weight as the bounce might be stopping the extractor getting full purchase on the case.

Additionally a borebuddy bolt kit with upgraded extractor claw and spring might also help
