Make sure the magazine is fully snapped into place. If the magazine is not fully seated, the pellet will not line up with the chamber, and the 'bolt' cannot go forward.
My Avenger rifles use the same magazine. It was a bit of a puzzle to figure out the loading of the magazine, and how to insert the magazine into the rifle.
What about options for an inexpressive scope? Something 2-7 or 4x maybe?
and THANK you guys.
Curious- what is the biggest thing you have tackled with this rifle?
I've only killed small pests (starlings and chipmunks) with the 22 cal Avenger. The basic Crosman 14.3gr hollow point does a number on them at around 1000 fps.
