This is a brand new rifle. Was sighting it in and all was good. After sighting it in I wanted to adjust the trigger. Turned it 1/4 turn aimed at the ground and went to pull the trigger. The trigger had the wall I wanted so I pulled for the 2nd stage and it was very hard to pull like the trigger was jammed. So tried it again and pulled hard and it fired. It was loud like a .22 rimfire rifle. Scared the piss out of me because I wasn't expecting it. So I tried again and it was normal. Has anyone encounter this before? Should I send it back to Amazon? Thanks for your help.....
