1) Hold the rifle sideways OR:

My gunsmith Bubba can help you out if you'd like. But Hey, if you ever owned a Tasco you'd have the answers already.

Seriously the guys at Vortex are good to deal with. I've dealt with them and you are good to go. It's a hassle of course to ship it back, but at least it will be fixed and usually done right.
