SIG SAUER TANGO-MSR Compact 1-6×24 LPVO with ROMEO1

SIG SAUER TANGO-MSR Compact 1–6×24 with ROMEO1

The SIG SAUER TANGO-MSR Compact 1–6×24 combines a short second-focal-plane low-power variable optic with a factory-installed compact MSR mount and an offset 3-MOA ROMEO1 red-dot sight. This exact black package, manufacturer part number SOTMC61000-R1 and UPC 798681725991, gives a modern sporting rifle both variable magnification and a dedicated close-range aiming option in one coordinated setup.

At 1×, the TANGO-MSR supports rapid target acquisition and a broad view for close-range work. Increasing magnification up to 6× provides more precision for target identification and deliberate shots at intermediate distances. The 24mm objective and 30mm main tube keep the optic streamlined, while the compact body measures only 8.4 inches long—approximately two inches shorter than the original TANGO-MSR configuration.

Illuminated BDC6 reticle

The illuminated BDC6 reticle places an easy-to-find aiming reference in the second focal plane. Because the reticle remains visually consistent in size as magnification changes, it is quick to pick up across the entire 1–6× range. The bullet-drop references can support practical holds after the shooter confirms actual impact data with the chosen rifle, barrel, ammunition, and environmental conditions. Illumination improves reticle visibility against dark or visually complex backgrounds.

A wraparound magnification throw lever provides positive control when moving between power settings. SIG SAUER’s SpectraCoat lens treatment helps manage reflection and supports useful light transmission, and the optic is designed to withstand the shock, moisture, and temperature changes associated with field and range use. Published eye relief is 3.7 inches at both low and high magnification, helping maintain a consistent head position during power changes.

Factory-installed mount and offset ROMEO1

The compact MSR mount arrives installed and leveled, reducing the setup work normally required for a new LPVO. The included ROMEO1 uses a 3-MOA red dot with multiple brightness settings and is positioned as an offset secondary sight. Rotating the rifle to the red dot provides a fast alternative to changing the scope’s magnification, while returning to the primary optic restores the magnified view. The combination is particularly useful for training that alternates between near and intermediate targets.

As with any mounted optic package, final installation still requires the user to confirm correct rail placement, fastener torque, eye relief, and zero in accordance with the manuals. Zero the TANGO-MSR and ROMEO1 independently, then confirm both from the shooting positions and ammunition that will actually be used.

Who this package is for

This package suits shooters who want one rifle to cover close-range speed, intermediate-distance precision, and transition drills without building the optic stack from separate components. The compact LPVO preserves useful magnification while the offset ROMEO1 provides an immediately available non-magnified aiming system. It is appropriate for range training, competition-style practice, and general-purpose rifle setups where space and versatility matter.

Before use, verify mounting and zero, inspect the lenses and fasteners, and confirm that both illuminated optics have serviceable batteries. Follow the firearm and optic manuals, maintain proper eye relief, and use appropriate eye and hearing protection whenever firing.
