I cant zero my scope
yesterday i went to the airsoft canada retail store and got the ACM sniper bundle as i thought it will be a good gun to start playing airsoft. however when i got my the scope was totally off so i decided to go online and do some research for the fix. I came across a few youtube video called zeroing your scope when i tried to turn the dial or the little circle piece it doesnt do anything and the scope model is tasco 3-9X40. thanks in advance.
