Guys I need some help from some of you that have a lot of experience with the BAM type rifles. I have a B25 in .22 caliber, the bamboo stocked version. Anyway when I cock it it will only engage when I pull the trigger at the bottom of the cocking stroke. I has a only a few rare occasions cocked with doing the trigger pull thing, but 98% of the time I have to pull the trigger to get it to fully engage. I had it apart last night and everything looked normal but upon re assembly it still act the same way. Any ideas?
