EXPS3-4 G45 eye box tight
Reviewed on April 21, 2026Verified with Build

EOTECH EXPS3-4 with G45 magnifier has excellent glass but the eye box is tighter than my red dot - takes a moment to find the reticle at speed. The G45 5x magnifier is sharp. Worth the cost for medium range engagement work.

EXPS3-4 G45 re-zero needed
Reviewed on February 21, 2026Verified with Build

EOTECH EXPS3-4 with G45 magnifier works correctly but zero shifted a touch after the first range session. Re-zeroed and its held since. Glass at 4x with G45 is sharp. Battery life is good. Solid premium hybrid setup.
