To meet the stringent requirements set and demanded by our elite fighting forces, L-3 EOTech has developed the SU-231/PEQ (Model 553), modeled after the ever popular, battle proven HWS design. The SU-231/PEQ (Model 553) incorporates many additional features required within the SOPMOD Block 2 program. This combat sight has been standardized as the weapon sight of choice by America’s warrior elite, the US Special Operations Command. Eotech has done it again by making the best even better.
