Mystery pistol. Challenger Arms Corp CO2 pistol with EAGLE ROCK 41 CALIF stamp. How can this be ???? Very, very, very unusual. Also stamped S 22, NEVER seen this stamp. We all have seen the C 22, 22, and no stamp at all. This gun came with box, paperwork, and the extremely rare 10 inch target barrel which is not shown in this post. I bought this about a week ago. I welcome all comments
