Nylon 66 amazes me at the bracket people want to put it in. It is a good plinker grade 22 rifle and will stand abuse. It is breakable, especially in sub zero temps. Pull dust cover off and you will see weakest area is in the bolt ways area. Scoping is attaching to a sheet metal dust cover. I always kept one around for kids because it was light. For this reason also a good utility gun. There were some very fine autoloading 22 rifles in Nylon 66 era. Just about any I can think of were more accurate than Nylon 66.
