Re: Norinko SKS
Mike, I'm not 100%, but with the SKS... The "spring" firing pins vs. the "floating" firing pins, was an after thought, the spring style was to prevent "slam fires". The SKS bolt and firing pins were tapered, and some times the firing pin got "stuck" protruding past the bolt face causing.... Barrrrrrrp!
I would ASSUME the AK has the same thinking!
Also.... The spring and floating for the most part are interchangeable on the SKS... I'm sure there is an exception somewhere.
Hope this helps,
You can't prevent the inevitable.. only alter its time span!
