2.1.9. Sights
The SIG516 rifle features integrated Mil-Std M1913 rails on the upper receiver and the Quad Rail Hand Guards. These
rails may be used for attaching a variety of sighting systems, both optical and fixed. Some models feature SIG SAUER flip
up front and rear sights as a standard feature. These sights are designed to provide a simple, durable sighting solution
should you decide not to use an optical device. Markings on all rail surfaces give you a reference point to reattach your
sighting system in exactly the same place should you need to remove it for service.
