    I have been giving a modern 9 32 scope but the rings are dovetails. Am I asking for the correct mounting configuration for a nylon 66?

    I believe that you need dovetail rings for the grooved top of the Nylon 66 receiver.

    Just google "dovetail scope rings". They also have a dovetail to picatinney rail adapter, if that would better suit you.

    Not to be hardheaded or arguemenitive if dovetails won't work on the cover picatinney rail doesn't seen the right fit

    This the dovetailed mounting ring

    I'd suggest using regular .22 mounts for grooved receivers, especially for an M-66. Picatinny rails add unnecessary height, bulk and weight.

    Thanks for the pic. Now I'm confused. You mentioned smaller 3/8 dove tails. What is smaller that groove is maybe. 040 wide
    The 3/8" dovetail rings are what's recommended for the m66 nylon. If you must put a scope on one, that would be the preferred route to go. Adding a pic rail is just junk stacking, giving you more to go wrong.

    Thanks everyone. I'm on the same sheet as ya'll now. I do believe the scope I have is a low profile flat type dovetail. I have seen examples of the 3/8 dove tail with a cove recessed in the upper mounting area that appears to be what I need.

    That was one point of confusion that the whole scope would be entirely to high

    Yup .

    40 years ago , you would have had to be careful not to get tipoff mounts intended for 3/4 inch scope tube, but nowadays everything is for 1 inch , if not 30mm , and you'd have to search hard to find 3/4 for a retro build .

    Also called '.22 Tipoff Mounts'. Got em at the Tackle Box in Lexington Park. I was still having trouble stopped over at Medusa Muntions table today they confirmed as well as most everyone else "yep dems the ones" Joe took 2 - 3 mins to show me I was wrong LOL. Thanks for the tips ya'll.
