The EXPS3 HD builds on EOTECH's holographic legacy with a refined, hoodless design that enhances peripheral awareness while maintaining fast, both-eyes-open engagement. Featuring a left-side rotary dial, adaptive auto-brightness, and shake-awake technology, it delivers intuitive control without sacrificing magnifier compatibility. Housed in durable all-aluminum construction, the EXPS3 HD maintains EOTECH's proven reliability with a 1.74" centerline height for a lower 1/3 co-witness. A modern evolution of a legendary optic.
