Things I liked:this is an amazing scope. i got it as part of a package on my Beretta XX-Treme. after shooing with it for a while i realized it is nearly parallax-free. i still can't hardly believe it, but it's as parallax-free as my $400 aimpoint scope. i just ordered another to put on my .22 handgun. Things I would have changed:it would be nice if there was an option for 3/8"/11mm rails.
