Nothing but trouble

This BCG has been the cause of more than one headache. I bought it on 6/22/2020 along with a complete M5E1 enhanced 22" upper in 6.5 Creed. No matter how much cleaning/oiling I do, the bolt gets stuck in the carrier. It is excessively tight when it should move smoothly and without much effort. Additionally, I've been having consistant light strikes/FTF. After examining today, I found the firing pin to be more than 1/32" too short. I borrowed a buddys pin from his .308 BCG and it fired perfectly round after round. I'm going to have to return this and hope for a more functional replacement.
