Fail to fire/light strikes and average accuracy - CMMG 22LR M4 Profiled Barrel and Collar Kit

First time I pulled the trigger, fail to fire. Rim of that round had the lightest strike I've seen. The adapter that fits over the snout of the barrel wasn't flush, it was set back causing the light strikes. Over the course of the next 200 rounds there were over 20 more fail to fires. Accuracy was okay. I was hoping it would be more accurate than the CMMG kit using a 5.56 barrel. Using the same ammo in both, they are about the same. Maybe I got a bad one. If the accuracy at 100 yards is no improvement over the CMMG kit and 5.56 barrel, I'll probably return it.
