Stopped in again this afternoon. Somebody picked up the .22lr version. The .22 mag version is still there.
I also noticed something else interesting besides the rifle itself. It is very difficult to line up the iron sights and maintain a good "heads up" position. The sight line is barely above the comb (drop at comb is too small). You almost have to lay your head over the "stock." For me, this rifle would only work with an optic. If you look at the model in the video, it seems that she has the same issue.
Very cool. Would make a nice little plinker. I wouldn't mind buying my son one of these. Have to break it open for every shot. That'll keep him on the fundamentals making sure they count.
