I can't remember what size dovetail scope mount is on the old rem 22's grove on top of the receiver like 550-1,572s etc. can some one please remind my stupidly please? I think it's a 3/8" but not at all sure. someone told me it is 11 mm. i'm 65 and don't know the metric system I'm still on American sizes. I never learned the metric system please help an old man. thanks

  I don't have a solid answer about the Rem grooves although I seriously doubt they were using any metric specs at that time but here's a quick help for the metric conversion. One inch equals 25.4 MM. Convert the inch measurement to .000" and multiply by 25.4.
  3/8"=.375"(X 25.4)=8.525MM
  This is pretty lofty math for such an early start.

  'some' imported .22's have the 11mm grove and take a special mount. all u.s. made .22's (that I've seen anyway) take the 3/8" grove rings.

  Agree, 3/8" for the original Weaver Tip-Off Mount. Which is 9.5mm on my calculator.
  
  It was a good while before foreign imports started coming along with 11mm dovetails.
