The Sig Sauer ROMEO8T-AMR 1x40mm Red Dot & JULIET3T-AMR 5x24mm Magnifier Black Combo Kit is a highly modular, professional-grade tactical optic layout built around Sig Sauer's proprietary Automatic Modified Reticle (AMR™) platform. This database kit combines the wide-aperture, titanium-shrouded 40mm red dot sight with a quick-detachable 5x power magnification micro module. Driven by internal magnetic tracking nodes, the combined layout automatically swaps your active holdover scales or dot styles the split-second the magnifier shifts in or out of alignment, granting operators instant ballistic adjustments on a 1913 Picatinny host system.
