PLEASE HELP!!!!!

HI AIRGUNNERS i ook my daystate air ranger.25 to the range and realized that when i load the gun or pull the bolt back the trigger is not the same. The first stage is rough and unpredictable. On the manual there is no way to change the first stage. The wierd thing is that when i pull the trigger to the second stage and release it then pull it again it is fine. For that shot.

Please let me know how to adjust the first stage or if you have a similar problem.

I will probably contact AoA

Chris
