My model 64 has been flawless since the purchase of it a few years back. With around 4000 rounds through it now it's starting to have Fell to fire issue's. I've tried different brands of ammo without any luck and have given it a good cleaning a few time's here lately. My question is, could it be the firing pin and can you change to hammer & bolt spring on the bolt? I notice that it's connected to the bolt and when I've cleaned the rifle I haven't figure out how to remove the springs from the bolt.
Any help would be appreciated - Brad
