After you set your zero, you can adjust the scope dial to match the zero on the scope dial scale. As you shoot and adjust your elevation for the distance you are shooting, its just a matter of turning the dial back to your original zero setting on the dial. It has a mechanical stop which will stop at zero on the dial scale.

At 59 this is best thing I've done. Takes a little practice both eyes open and look for front site will bring you right to the dot.

Love this viper red dot optic, would recommend to any one thinking of purchasing one!

The RMR HD improves on everything the RMR does. Top loading battery, bigger windows, better auto brightness, everything is great. I'd pay a little more for the HD over the Holosun product.

Got my TX22 about 2 months and installed a Sig Romeo Zero red dot on the Lakeline dovetail mounting plate. Took an hour to get the Lakeline plate filed and sanded according to the instructions to fit the dovetail and it works great. The Romeo Zero mounts perfectly with the screws provided by Lakeline
