SIG Sauer Tango MSR 1-6×24 30mm Illuminated BDC6

SIG Sauer Tango MSR 1-6×24 — low-power variable rifle optic. This LPVO provides variable 1–6x magnification for rapid target acquisition and adjustable sighting at short to mid distances.

The Tango MSR is designed as a tactical rifle optic that combines a 6x optical system with an illuminated MSR BDC6 reticle on the second focal plane. It is intended for use on tactical rifle platforms where a durable, quick-acquisition optic is required for dynamic engagement distances. The scope includes an ALPHA‑MSR one‑piece cantilever mount for installation on compatible receiver rails.

• Magnification: 1–6x variable power for close- to mid-range engagement.
• Objective lens: 24 mm objective diameter for a compact front profile.
