"The SIG SAUER Romeo8T-AMR Red Dot and Julet3T-AMR Magnifier Combo Kit is an all-in-one solution for ""smart"" targeting during close- and mid-range engagements. Inspired by the original Romeo8T, the Romeo8T-AMR is over 30% smaller and lighter than competing holographic sights. When used in conjunction with the Juliet3T-AMR Magnifier, the Romeo8T-AMR utilizes SIG's revolutionary Automatic Modified Reticle technology to instantly change the reticle type and brightness when engaging or disengaging the Magnifier via magnetic sensors. This allows you to seamlessly transition between different holdovers at 1x and 3x magnification without needing to adjust the reticle manually. And while the Romeo is over 30% smaller and lighter, it still boasts a massive 40mm objective lens for an unrivaled field of view while advanced lens coatings provide enhanced clarity during daylight and when used with night vision. The Romeo8T-AMR and Juliet3T-AMR are engineered to exceed the demands of elite warfighters around the world. Both units meet MIL-810-STD protocol, are waterproof and fogproof to IPX8 standards, and are fully covered by SIG's Infinite Guarantee.
