EOTech 553 - Manual (Page 36)

Model SU-231/PEQ (M553):
1. Pull and turn the two throw-levers so they are away from their closed and nested position in
the base of the sight. This will turn the securing lip of each throw lever outward and allow the
sight to mount onto the rail.
2. The sight contains a small post that rests in the groove of the Picatinny rail. Move the sight
to the position desired on the rail and allow the post to rest fully in the closest groove.
3. Push the sight as far forward as possible and close both of the throw-lever arms so they are
fully shut and nested in the base of the sight.
