Does any one know where to find a manual on install/set up of an M84 scope on a M1D ( newly installed barrel with barrel block, thanks Tim for the install job). I have had no luck, so I went and bought a original GI scope mount and M-84 scope. Shoots consistently to right and low (Same with new made reproduction scope). Afraid to monkey around under the caps with out a manual, video etc. least I screw. Thanks forward. Patrick
