Bolt face is too big for .223/5,56 - CMC Triggers Enhanced AR Bolt Carrier Group (BCG)

Bought 2 of these and both will not eject the fired round, resulting in stuck case in chamber, one was sent back and waiting to arrive (but more than likely will have same issue) also tried on several other uppers with same result, had to use another BCG to extract case. I don’t know how people are getting them to run on their builds but I’ll be returning both more than likely.
