I’m not sure where this should be posted but since I need a part for a scope perhaps here is a good start. I gave a grandson a Remington 700 in 243. Rifle has a 3-9x40 Nikon monarch scope on top. The boys have graduated to bigger rifles now, so they returned to me the rem 700. The cap screw cover that protects the top (elevation) adjustment is missing. Does anyone know where I could find one? I’ll buy the pair is necessary. Thanks for looking.
