Hello Lancaster,

Thanks for your reply.

Do you have any idea what the other symbols and letters mean?

As a side note, I really like this rifle's unusual front sight. It has a small bead at the front, and when you push it down with your finger, "up" pops a "low-light" sight. And, when you push it down, "up" pops the front bead again. Its like a little built in teeter-totter.
