The Definition of Model 70 Type Safety
Model 70 Type Safety
A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire),
halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe).
While, like the Mauser, commendable for locking the firing pin instead of just the trigger,
its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights,
reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.
