I have a L61R 30.06 that my dad left to me. The gun is in really nice shape, except that the finish on the stock appears to have been damaged by cleaning solvent. In any event, it appears that a special tool is needed to disassemble the gun, and I would need to know the torque settings etc when reassembling it. Is there a video out there on how to do this, or could someone provide advice on the matter? Thank you.
