Surplus SU-231A Eotech EXPS3

Surplus marked SU-231A. These are the real deal.

The EOTech SU-231A/PEQ is a military-specific designation for the holographic weapon sight (HWS) based on the civilian EXPS3-0 model, issued by the U.S. military for use on platforms like the M4 carbine and SCAR rifles. It's an upgrade from the earlier SU-231/PEQ (based on the EOTech 553), designed for faster target acquisition in close-quarters combat.

This optic is great for MK18 and various other clone builds.
