I bought two scopes at WalMart yesterday. One is the 3-9x32 ($56) and the other is a 4-16x40 mm ($69). They are both Center Points. I didn't open the 40mm one because it looks massive. But, I did open up the smaller one and I couldn't mount it because the mounts don't fit. I think I am going to return both of them and get something else. I do want an adjustable zoom. Any sugesstions?
