Air rifles afford the serious shooter the opportunity to practice without the noise or cost of conventional rifles. Gamo air rifles are becoming increasingly popular with American shooters due to their blend of affordability and quality. A significant advantage of a Gamo air rifle is its adjustable trigger pull. The rifle is fitted with Gamo's standard two-stage adjustable trigger unit, which can easily be adjusted by manipulating the slotted screw directly behind the trigger.

  1. 1

    Cock your Gamo air rifle (without loading it), point the muzzle in a safe direction, and test fire it. Assess the current trigger pull based on your test fire. If the pull is too heavy plan on decreasing it; if too light plan on increasing it.

  2. 2

    Insert a small flathead screwdriver through the hole at the rear of the trigger guard and access the adjustment screw located directly behind the trigger.

  3. 3

    Increase the trigger pull by turning the adjustment screw in a counterclockwise direction or decrease the trigger pull by turning the adjustment screw in a clockwise direction.

  4. 4

    Fire the air rifle again to test the new trigger pull setting.

  5. 5

    Repeat this procedure until you are satisfied with the amount of trigger pull.

Tips and warnings

  • Remember that your Gamo air rifle is not a toy and should be handled with the same care as a conventional rifle. Improper use can result in serious injury or even death.
