Mohawk
Nylon 66
I have 3 different kinds of Nylon 66 rifles, but cannot remember ever shooting one.
Those are 77's.
They are indeed, I bought a Mohawk Brown 77 in '71 or '72, tried hard to wear it out for several years, then traded it to a friend, it has taught a bunch of kids to shoot in the last 50 years. It was a bit finicky about ammunition, but if you stayed with CCI's it ran like a top.
