After extensive testing of various optical sights, US Special Operations Command has standardized on the HWS as its 1X weapon optic for close quarter, urban combat zones. 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.

Standardized as the weapon sight of choice by America\'s warrior elite, the US Special Operations Command.
