Tikka T3 trigger adjustments depend on the model of rifle.
To adjust the Tikka T3 trigger, you will need a screwdriver that fits the adjustment screws.
First, identify which screws need to be adjusted. The vertical position and first stage screws are typically identified by arrows on the trigger housing. The horizontal position screw is typically identified by a hole in the housing.
Once you have located the adjustment screws, use a screwdriver to turn them clockwise or counterclockwise to make the desired changes.
Always review your owner’s manual before making any adjustments to your firearm.
