It looks like Chris From The 740 is disappointed with the  Hexion Tech Seeker Red Dot from Strike Industries. This is a compact and modular open reflex sight for pistols. It features three optional shrouds (small, medium, and large) for enhanced reticle visibility and protection. With 8 brightness settings, 3 reticles, and 4 modes, the Seeker offers versatility and ease of use.
