Query: red dot scope

unusable, better off with iron sightsi got this scope to replace my 15 year old tasco red dot on a .22 caliber hand gun, thinking it should have new technology and improvementsnot so, switch does not function properly and has to be moved back and forth to make a good contact and to remain onpower setting markings on the dial are not aligned correctly and off setting is somewhere at the number four mark???? - could not adjust itred dot is not a "dot" but a blurry star like apparition that is spread out in all directions on the internal prism, making aiming impossible even at lower power settingsanyhow, i do not know if these scopes are all this bad or just the one i had, but i will not buy another bushnell productreturned for refund
