The SIG Sauer ROMEO8T-AMR + JULIET3T-AMR Combo Kit pairs a full-size 1x40 enclosed red dot with a 3x22 micro magnifier in one package, built around SIG's Automatic Modified Reticle (AMR) technology — the reticle automatically transitions between configurations as the magnifier is engaged or disengaged.
The ROMEO8T-AMR uses a large 40mm HDX multi-coated lens with the QBCD 2.0 reticle, runs 50,000 hours on a CR123 via MOTAC (with a dedicated NV override and 15 settings), and is IPX8 waterproof and MIL-810 rated. The JULIET3T-AMR magnifier ships on a Powercam90 quick-release mount.
