While reading the threads for the manual for the Nyon 66 someone had asked where they could purchase parts for the 66 and 76. I came across the website below. It looks like it would be a good site for parts.
I have the manuals in a PDF format but this system will not allow me to upload the document it is too large. If you would like the manuals (3) please post your email and I will send them to you.
ok i had to take apart my nylon 66 to replace the cartridge stop spring and the cartridge feed insert came out ive whatch vidieos on you tube and on mynyolnrifles.com and had no luck putting the insert back in i need help cause i love this lil gun
There used to be a site called nylonrifles but it does not exist. You may want to go to http://www.rimfirecentral.com
I have a 66 and all the Remington schematics shows the #13 cartridge stop spring over the #12 cartridge stop pin BUT it should go UNDER the pin so there is spring tension.
It took me forever to figure this out.
good luck
