How to Sight in a Scope on a Gamo Air Rifle

Updated November 21, 2016

Gamo produces high-precision air guns that are suitable for competition, small game hunting and training. Gamo rifles are spring loaded and can fire pellets at velocities up to 1,200 feet per second. The accuracy of Gamo air guns combined with a low cost of pellets make using one an inexpensive method of developing your marksmanship skills. Sighting-in a scoped Gamo air rifle is similar to sighting-in a traditional rifle but involves a higher degree of trial and error.

Set up a target at a range of approximately 30 feet. Take careful aim at the centre of your target and shoot the Gamo air gun at least three times. Check your target for the shot group and mark the centre of the group with a piece of tape.

Adjust the scope's crosshairs based on the point of impact in your shot group. If your shot group is low and to the right, then the crosshairs must be moved up and to the left. To move the crosshairs up, rotate the adjustment dial on top of the scope counterclockwise or rotate the dial clockwise to move them down. To move the crosshairs left, rotate the adjustment dial on the right side of the scope counterclockwise or rotate the dial clockwise to move the crosshairs left.

Set up a new target at a range of approximately 75 feet and repeat the zeroing-in process in Step 1. Repeat until you’re satisfied with the results.


Exercise safety when sighting-in your rifle, Gamo air rifles are very powerful and can cause serious injury.
