Low-profile, flattop-mounted, polymer sights deploy instantly at the
touch of a finger to provide backup sighting if a primary optic fails.
Streamlined contours mean theres nothing to snag on brush, sling, or
other gear when folded. Spring-loaded ambidextrous release mechanism
lets you hit the grooved tab on either side of the sight to deploy, and
lock it in place. Hitting the same tabs retract the sight when you're
done. Uses less than 1" of MIL-STD 1913 Picatinny receiver rail space
and locks securely in place with the included steel crossbolt. Provides
the same height over bore as standard A2 iron sights. Front sight must
be mounted on a railed forend on the same plane as the receiver rail to
witness correctly with rear sight. Not compatible with railed gas blocks
or the MOE handguard.
