SIG SAUER P556 - Manual (Page 16)

Emergency sight deployment
The pistol’s emergency sights are normally stored in a “stowed”
condition to protect them from damage and prevent interference
with optical sighting systems.
To deploy the emergency sights for use, do the following:
1. Flip the front sight blade into the “up”
position. The front sight blade is retained
in position by spring tension.
2. Flip the rear sight blade into the “up”
position. The rear sight blade is held in
position by spring tension.
3. When the emergency sights are no longer
required, rotate the front and rear sight blades to their
stowed position.
