ive had my model 10fp in .308 for about 6 months now and ive put probobly 500 rounds through her so far. i felt it would be necessary to disassemble the bolt and clean it. is this necessary? is it simple? i read some stuff talking about setting the firing pin protrusion, how do i do this if i screw it up? i was also looking at the tactical bolt handle. would it be worth while to just have my original one threaded and add knobs to it? instructions and dangers on how to disassemble the bolt would be great.pictures work best for me!! will i get springs and stuff shooting out at me when i take it apart?
