Got a Cooey single shot 22 ( not sure of the model number ) that I have an old 3/4" rim fire scope on... been a while since I looked at it but I don't remember any issues scoping it...
so it's a bolt action repeater, or is it a single shot ???
mine the striker must be pulled back manually to cock it... probably keeping very little kids from using the gun, as I assume it was marketed as a kids rifle...
... I originally kept mine around for my nieces & nephews... though they've all grown up now
i tried to find info when i first got it but couldent find much one of my family members says its rare hes never seen a cooey maybe hes right most of my guns are rare.
I did some digging and I found that the HW Cooey Arms and Manufacturing model 60 repeating .22 was made between 1939-1940. I had 2 of them one with a scope and one without but I traded the one without the scope for a Ruger 10/22.
