SIG SAUER TANGO MSR Compact Scope 1 6x24mm 30mm SFP with Mount and Offset ROMEO1 Black SOTMC61000 R1 UPC 798681713462
Product Description
The SIG SAUER® TANGO-MSR Compact 1-6x24mm Combo (SKU: SOTMC61000-R1 / UPC: 798681713462) is a turnkey, dual-optic sighting system engineered for modern tactical carbines, patrol rifles, and 3-Gun competition builds. By compressing the proven TANGO-MSR optical architecture into an ultra-compact 8.4-inch chassis and pairing it with a factory-matched Alpha-MSR cantilever mount and an offset ROMEO1 micro reflex sight, this package delivers seamless transition from true 1x close-quarters target acquisition to 6x mid-range precision without breaking cheek weld or manipulating a throw lever under stress.
Constructed from aircraft-grade 6061-T6 aluminum and finished in a non-reflective MIL-A-8625 Type III hardcoat anodize, the 30mm main tube is purged with dry nitrogen and O-ring sealed to achieve an IPX-7 waterproof rating. Low-dispersion glass with SpectraCoat™ anti-reflection multi-coatings maximizes light transmission across dawn and dusk engagements. Inside the Second Focal Plane (SFP), the illuminated MSR BDC6 reticle provides calibrated holdovers out to 600 yards with 11 brightness levels, while the companion ROMEO1 features a CNC magnesium housing, molded glass aspheric lens, and MOTAC™ motion-activated illumination for instant readiness.
Built for modular rail efficiency, the shortened 8.4-inch footprint frees up valuable upper receiver and handguard rail space for clip-on night vision devices, thermal imagers, or infrared laser modules. Included factory flip-back lens covers, an integrated thread-in throw lever, and an aluminum 45-degree offset Picatinny mount make the SOTMC61000-R1 ready to torque onto any MIL-STD-1913 flat-top receiver straight out of the box.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Compatible with all MIL-STD-1913 Picatinny flat-top receivers (AR-15/M4, AR-10/SR-25, SIG MCX, SCAR, and PCC platforms). CRITICAL WARNINGS: Do NOT mount the Alpha-MSR base onto Weaver-style bases. Do NOT bridge the cantilever mount across the upper receiver and handguard gap—clamp the base strictly onto the monolithic upper receiver rail. The included ROMEO1 uses the original SIG ROMEO1 mounting footprint (M4x0.7 screws) and is NOT compatible with RMR or RMSc offset plates. Torque specifications: 65 in-lbs for the Alpha-MSR cross-bolts to the Picatinny rail; 18–20 in-lbs maximum for the 30mm scope ring cap screws (dry threads, no threadlocker); 15–18 in-lbs for the ROMEO1 mounting screws with a drop of medium-strength blue threadlocker.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty before staging optics on the bench.
- Degrease the upper receiver MIL-STD-1913 Picatinny slots and mount cross-bolts, then push the Alpha-MSR cantilever mount forward against the recoil lug shoulders before torquing cross-bolts to 65 in-lbs.
- Place the TANGO-MSR Compact 30mm tube into the lower ring saddles, establish proper eye relief (3.7"–3.9") at 6x magnification in your natural shooting stance, level the reticle with a plumb line or bubble level, and torque ring cap screws evenly in a criss-cross pattern to 18–20 in-lbs.
- Install the 45-degree offset Picatinny mount onto the upper receiver rail (fore or aft of the primary mount depending on shooter preference), torque the rail clamp per manufacturer spec, and secure the ROMEO1 reflex sight to the offset plate at 15–18 in-lbs using blue threadlocker.
- Confirm crisp 0.5 MOA turret tracking, verify illumination function on both the MSR BDC6 reticle (CR2032) and ROMEO1 MOTAC system (CR1632), and confirm zero both optics at 50/200 yards (primary LPVO) and 25 yards (offset red dot).
Key Features
- Ultra-Compact 8.4-Inch LPVO Chassis: Shortened overall footprint saves 2.2 inches of rail space compared to standard 1-6x24 optics, accommodating clip-on NV/thermal units and forward laser devices.
- Turnkey Dual-Optic Redundancy: Includes the factory-matched Alpha-MSR 30mm cantilever mount and a 45-degree offset SIG SAUER ROMEO1 reflex sight for instant 1x transitions without adjusting magnification.
- Illuminated MSR BDC6 SFP Reticle: Second Focal Plane reticle with 11 brightness settings and ballistic holdover subtensions calibrated for common 5.56 NATO / .223 Rem and 7.62 NATO trajectories.
- MOTAC™ Motion-Activated Technology: The bundled ROMEO1 powers up immediately upon sensing motion and powers down during periods of inactivity to maximize CR1632 battery runtime.
- Tactical Hardware Included: Ships complete with a removable thread-in magnification throw lever and lay-flat flip-back objective and ocular lens covers.
- Rugged IPX-7 Waterproof Construction: Nitrogen-purged, O-ring sealed 6061-T6 aluminum main tube resists fogging, heavy recoil, and full water immersion.
