it is a smk 19 air rifle with standard scope mounts and richter optik 6x40 scope. it also has a silencer if that helps.
Was it working ok before, or have you changed something?
it has been set up perfectly before. i got it in october last year and it has been set up for a while but i noticed about a month ago it was out so i got my grandad to set it up a few days ago and he couldnt get it down any further so my uncle tried but he cant get it any thurther down. i cant either. i havent changed anything.
