AW vs. L96A1 Safety Details
AW 3-position safety is similar to Winchester Model 70. The safety lever is on the right side of the shroud body, position as it appears when looking down from above:
Forward (1 o'clock) - Firing pin and Bolt unlocked (firing position)
Middle (3 o'clock) - Firing pin locked, Bolt operable ("1st Safe," best position to unload a round)
Rear (5 o'clock) - Firing pin and Bolt locked ("2nd Safe," fully safe position)
L96A1 2-position safety is on the LEFT side of the shroud body, position of lever as it appears from the LEFT side of the rifle:
Forward (9 o'clock) - Firing pin locked, Bolt locked from moving backward, but you can still rotate/unlock the bolt (Safe position, "white dot" visible)
Rear (3 o'clock) - Firing pin and Bolt unlocked (firing position, "red dot" visible)
Hope that helps.
