I have a TM VSR
the sears went bad recently so I decided to get the airsoftgi upgrade pack
1. sear and piston set
2. spring guide
3. piston
I have the gun back together the bolt pulls back, round is chambered, push bolt back. everything is functioning right.... unit I go to pull the trigger.
I pull the trigger and there is a pull to it but nothing happens. Why is this?
PLEASE HELP!!!!!
