I placed an order for a couple of nice scopes for the 10/22's of my father and I to use for the Appleseed event coming up this month. Unfortunately, it doesn't look like they're going to be here in time (good deal but long lead time). Currently mounted on my gun is a Vortex Crossfire 2 3-9x50mm which works fine with the adjustable objective but quite big and heavy at 18.4 ounces. He doesn't yet have a scope, but will need one for the event. Bonus points if we can use the existing 1" rings we bought. Any suggestions?
