Streamlined Optics for Modern Shooting Applications
SIG Sauer has unveiled their latest addition to the TANGO riflescope family with the introduction of the TANGO-MSR Compact series. These low power variable optics (LPVOs) represent a significant evolution in compact scope design, delivering professional-grade performance in a remarkably lightweight and shortened package that addresses the demands of today's tactical and sporting rifle platforms.
Design Philosophy: Compact Without Compromise
Reduced Profile, Enhanced Performance
The engineering focus behind the TANGO-MSR Compact series centers on weight reduction and size optimization without sacrificing optical quality or durability. These new models achieve a 20% reduction in both length and weight compared to their predecessors, measuring just 8.4 inches in overall length while maintaining a minimal 14.5-ounce weight profile. This compact footprint makes them particularly well-suited for carbine platforms where every ounce matters.
Model Variants and Specifications
TANGO-MSR Compact 1-6x24mm (SFP)
The entry-level model in the series offers 1-6x magnification with a 24mm objective lens in a second focal plane configuration. This scope targets shooters who prioritize straightforward operation and proven reliability over advanced features.

Key Specifications:
- Magnification: 1-6x
- Objective Lens: 24mm
- Focal Plane: Second (SFP)
- Length: 8.4 inches
- Weight: 14.5 ounces
- Reticle: Illuminated MSR BDC-6
- MSRP: $399.99 (with mount)
The package includes a factory-mounted ALPHA-MSR aluminum cantilever mount, providing immediate installation capability and ensuring proper scope alignment. For users with existing mounting solutions, a mount-free version is available at approximately $100 less.
TANGO-MSR Compact 1-8x24mm (SFP)
The higher magnification variant extends the useful range with 1-8x magnification while maintaining the same compact dimensions and weight characteristics.

Key Specifications:
- Magnification: 1-8x
- Objective Lens: 24mm
- Focal Plane: Second (SFP)
- Length: 8.4 inches
- Weight: 14.5 ounces
- Reticle: Illuminated MSR BDC-8
- MSRP: $499.99 (with mount)

This model includes the cantilever mount, protective flip covers, and the MSR BDC-8 reticle specifically calibrated for the extended magnification range.
Advanced Features and Technology
Optical Performance
The TANGO-MSR Compact series incorporates low-dispersion glass elements designed to deliver crystal-clear edge-to-edge visual performance. This optical technology minimizes chromatic aberration and maintains image sharpness across the entire field of view, ensuring consistent target identification at all magnification levels.
Illumination System
Both models feature a 6-setting illumination system that allows shooters to adjust reticle brightness according to lighting conditions. The illuminated reticles maintain visibility in low-light scenarios while preventing over-illumination that could compromise night vision.
Durability and Protection
Environmental Sealing
All TANGO-MSR Compact models meet rigorous environmental standards, offering:
- Waterproof construction
- Shockproof design
- Fogproof performance
Lens Protection
Integrated flip-back, lay-flat lens covers provide protection for the objective and eyepiece lenses during transport and storage. The low-profile design ensures these covers won't interfere with shooting positions or equipment placement.
Operational Enhancements
TANGO6T-DVO Throw Lever
Each scope includes a removable TANGO6T-DVO throw lever that enables rapid magnification changes. This ambidextrous lever can be positioned according to user preference and removed entirely when not needed, maintaining the scope's streamlined profile.
Mount Integration
The included ALPHA-MSR aluminum cantilever mount provides a solid mounting platform while contributing to the overall system's lightweight characteristics. The cantilever design offers proper eye relief positioning for AR-platform rifles and similar carbine configurations.
Target Applications
The TANGO-MSR Compact series addresses multiple shooting disciplines, from tactical applications requiring rapid target engagement at varying distances to sporting applications where weight savings and reliable performance are priorities. The compact dimensions make these optics particularly attractive for patrol rifles, home defense carbines, and competitive shooting platforms where maneuverability is essential.
