That lower was made in the early 60's, if I had to guess. Very cool.

If the auto sear uses a torsion spring how is the long leg of the spring (that rests on the selector) able to be moved freely without exerting force oppositely like a standard torsion spring? Can someone with some knowledge on these explain?

[@apocalypticredix8538]

is this a pre 86 lower?

[@FloridaMan762]
