This is my first purchase from Ghost Rifles and I have to say I’m thoroughly impressed. Considering the current economic situation the shipping was not that long of a wait and although short, it was well worth it. The upper does have a cerakote finish for those who may not have seen it in the description and the coating does add some thickness to the inner pin holes. Other than the struggle to get it to secure to the lower (due to the cerakote finish); once it went through, the rifle felt great in the hands. I have not had a chance to shoot through the upper but when I do I will be 100% sure to update this review. NOTE: For those who have 300 AAC Blackout chambered rifles, your BCG and CH will pop into this upper and shoot 5.56.
