Thanks for the info guys. I'm going to give it a go with the open sights at the range tomorrow and see how it shoots.

Looking at it, there's probably enough room on the over-lever to mount a red dot sight right at the front and still have enough room at the back to push it closed. Just got to learn to keep my pinkies out of the way when it snaps shut.

I notice Bill says they're pellet fussy. What pellets do you guys recommend? I blagged a tin of Geco wadcutters free with it, but i've never used those before at all.
