There are now three models of the L-3 EOTech holographic weapon sight counterfeits
that are in the market, primarily sold through web sites based in China and Korea, EBay,
and at local gun shows. They are the Model 552 which utilizes two AA batteries, the
Model 551 which uses two N batteries and the model 553 (Military designation – SU-
231/PEQ) which uses two CR 123 batteries and has two quick detachable throw lever
mounts. Genuine and counterfeit L-3 EOTech holographic weapon sights are shown in
Figures 1, 2 and 3 for the three models. The sight on the left is a genuine L-3 EOTech
holographic sight and the one on the right is a counterfeit. As one can see, the outside
appearance is nearly identical. Also note, the counterfeit Model 553 sight shown in
Figure 3 has the L-3 EOTech logo imprinted on it.
