The SIG Sauer ROMEO8H is a full-size enclosed rifle red dot with a wide 38mm aperture for a generous both-eyes-open sight picture. The sealed emitter keeps the dot running through rain, dust and debris, and the aluminium housing makes it a lighter alternative to the titanium-shrouded ROMEO8T while keeping the same versatile reticle system.
It runs a quad Ballistic Circle Dot reticle (4 selectable modes: 2 MOA dot, 65 MOA circle, with/without holdovers), MOTAC motion activation and over 100,000 hours on a single CR123A. IPX8-rated, with an integrated Picatinny mount.
