I recently disassembled my .308 and cant remember how to put the firing pin in. Here are the photos. I cant remember how I am supposed to put the piston and bolt in with the firing pin. If I leave the firing pin out it will slide in perfectly. Please help. The first phot is the firing pin and the second is me trying to get the piston and bolt in with the firing pin inserted...as you can see it doesnt fit.
