The SIG SAUER TANGO6T DVO is a 1-6x24mm first focal plane low-power variable optic in Flat Dark Earth, the commercial version of the direct view optic SIG builds for the U.S. military, set up for AR-15s and other 5.56 carbines. At 1x it lets you shoot with both eyes open, much like a red dot. At 6x the DWLR-556 reticle gives MRAD-based drop and wind holds for 5.56 ammunition at mid-range distances. It comes installed in SIG's ALPHA4 cantilever mount, which SIG says has been widely fielded by the Department of Defense, and includes magnetic lay-flat flip-back caps and an anti-reflection device that cuts glare off the objective lens.
This configuration, SOT61DVO, pairs the FFP DWLR-556 reticle with capped 0.2 MRAD turrets and the FDE finish. SIG lists the DWLR-556 TANGO6T with parallax fixed at 300 meters, where most other TANGO6T 1-6x24mm reticles are set at 150 meters. Because the reticle is in the first focal plane, its holds stay correct at any magnification. Daylight and night-vision-compatible illumination settings sit on one locking dial.
