Must have for cmmg banshee - CMMG Mk10 Ejector Spring

Written on September 21, 2024
After about 400rds on a 5.5" 9mm banshee, I started getting strange jams and what I thought was failure to extract. Bought the bcm extractor upgrade and it made the problem worse. Looking on forums, it was advised that it was an ejection issue and the mk4 springs were weak from the factory
