I have had nothing but trouble putting my roller back together after the trigger spring replacement. This is the easiest rifle to disassemble and yet can't get the hammer back in. The hammer spring is stopping me dead. The only video I can find is Larry Potter on utube. I am doing it the same as him but I can't get the hammer to properly engage the hammer spring. Any ideas? Any videos out there that I can't find? Any help would be most appreciated.
