Sig Sauer’s line of TANGO-MSR Low Power Variable Riflescopes have been the winner’s of three consecutive U.S. Military contracts: the Squad Designated Marksman Riflescope (SDMR), the Squad Variable Powered Scope (S-VPS) and the Direct View Optic (DVO) programs. They ship with the ALPHA-MSR cantilever mount, and come with exclusive features such as flip-back lens covers, a removable thread-in throw leaver, and eleven illumination settings. To ensure accurate target engagement at extended ranges, the TANGO-MSR is equipped with the BDC reticle. This reticle is composed of a free-floating dot in the center of a semi-circle, that sits atop a pyramid structure of hash marks a holdover points to accurately compensate for bullet drop and wind drift.
