These are different than what nfc is using. We build exclusively on nfc blanks and they make amazing blanks! I believe they are actually making their new grips the same way they build their blanks. I think they are using mandrels but I'm not sure. We are using a different technique. It will not be used in mass production because of the time it takes to make them. I cannot take credit for the idea of these grips but the way we build them and figuring out a way to make it efficiant is the difficult part. Also making the grips look perfect takes a lot of practice. Some builders make them on the east coast but they are rare.
