i got a 5x burris scope with AO from a member here and i like that scope.then i got ahold of a 3-9x Burris with AO and ive been shooting with that on my new 22 match barrel.then my shooting friend showed up with a 3-12x Burris with AO on his match chamber and i spent some time with that gun and scope and all i have to say is WOW.these are pistol scopes.the Bushnell and Leupold scope that i have may go down the road.i can see one of those 3-12s in my future on my 22 match barrel and that 3-9 on my 357max barrel.i can see why the sillywet shooters are using them.ive got to spend the more money$$$$
