1.2 Key Attributes
The SU-231/PEQ (M553), M552, and the M551 reflex sights are lightweight, non-
magnifying, optical sights designed for Close Quarter Battle. They allow very fast
target acquisition and engagement at short ranges while providing aiming capability
out to 300 meters equal to or better than iron sights.
The major combat advantage of the reflex sight is extremely rapid reticle-on-target
acquisition. As quickly as a target is identified, the holographic reticle can be
superimposed on the target. The sight allows operators
to maintain eye contact on the target and to place the
holographic reticle onto the target without shifting focus.
Operators can quickly acquire the target and reticle in the
same focal plane for fast and accurate shot placement.
The reflex sight appears to project the holographic image
of a reticle on the target plane. The sight can be used as
a bright open reticle image or a fine dot which is limited
only by the acuity of the shooter’s eye. The reticle
pattern is parallax free and the holographic heads up display window allows an
undistorted and unrestricted view of the target.
The reflex sight standard reticle is displayed in Figure 1: 65 minute ring with vertical
and horizontal stadia and a one MOA aiming dot.
