I haven't seen the Flip Over mounts & rings in years. I doubt if they are even made any longer.As far as See Thru's. If I had to use the See Thru's or no scope at all I would go without a scope. The See Thru's are nothing but trouble.They sit to high to begin with,they are made of aluminum extrusion. The slightest bump and your scope is knocked out. I have a gunsmith friend who has a wall full of them he's taken off customers guns.They might be alright if they were steel which I have never seen steel S.T.'s. Do what you think but I assure you you'll regret the See Thru's.
