I will e-mail a copy of this as well.
First of all, we need to determine if it is a factory built preban rifle. Chances are, it is not. During that period, most of our lowers were being sold as stripped rather than rifles.
If it is determined that it's not factory built, then it's anyone's guess who's parts were used to finish it, and what specs they are made to, if any.
If you can provide me with some more details on it, I can check into it's origin, and we can go from there.
