Tuning Beeman R 1

Yep...either some one messing with the trigger or...had this happen some years back, a pellet got into the trigger mechanism, probably a loose one floating around in the case, worked its way into the nechanism and locked it up!! This was a 177 cal model, cant see that happening with a 22 as I believe the 22 pellet is to big to slip inside, how ever it might be other crud. Try flushing the trigger mechanism with aerosol cleaner.
