Details:

If you want your shots to be on target at long ranges, you need to have your crosshairs leveled perfectly. Some alignment tools on the market level the crosshairs to the scope base or another arbitrary and inconsistent point. The Level-Level-Level scope crosshair alignment tool from Wheeler Engineering is a far better option.

It works by aligning your scope with the top of the receiver, which is the most accurate point. The leveling can be done in minutes with this tool. You simply attach the first level to the receiver, place the other level on any flat point on top of the scope, and orient the scope so that the two levels match up! It fits most popular bolt action rifles, and it can be adjusted to fit more obscure designs. Keep your bolt action rifle consistently on target with the Level-Level-Level scope crosshair alignment tool!
