Sig Sauer TANGO4 Scope 6-24x50mm 30mm SF MRAD FFP with Illuminated Reticle

Clear Product Overview

The Sig Sauer TANGO4 6-24x50mm 30mm SF (Side Focus) MRAD Riflescope is an elite long-range optical instrument engineered for tactical precision shooters, Precision Rifle Series (PRS) competitors, and long-range hunters. Produced by Sig Sauer Electro-Optics, this First Focal Plane (FFP) scope pairs high-magnification $6\text{x}-24\text{x}$ optical resolution with a 50mm objective lens, side focus parallax adjustment, and a precision-milled illuminated MRAD reticle in an anodized black housing.

First, the TANGO4 6-24×50 SF features Sig Sauer’s signature HDX glass optical system, combining extra-low dispersion (ED) lens elements with high-transmittance glass. Consequently, marksmen experience sharp edge-to-edge resolution, vivid target contrast, and color fidelity when locating downrange targets at distances beyond 1,000 yards. In addition, its First Focal Plane (FFP) reticle design ensures that all MRAD crosshair hash marks and holdover subtensions remain 100% accurate across every magnification setting from $6\text{x}$ to $24\text{x}$. Furthermore, the integrated Side Focus (SF) parallax dial allows rapid adjustment from 10 yards to infinity, while MOTAC (Motion Activated Illumination) technology automatically powers the reticle illumination on upon sensing motion and shuts it off when stationary to preserve battery life. Therefore, it delivers exceptional mechanical tracking accuracy, fast parallax elimination, and long-range optical precision.

Real-World Use Information

Precision marksmen and tactical shooters choose the Sig Sauer Tango4 6-24×50 SF MRAD for bolt-action precision chassis setups (such as 6.5 Creedmoor, .308 Winchester, or .300 Win Mag) and long-range AR-10 DMR rifles. Consequently, operators engaged in dynamic long-range shooting drills can quickly eliminate image parallax blur using the side-focus dial while making instant elevation and windage holds on the MRAD reticle.

Additionally, the $6\text{x}$ to $24\text{x}$ magnification ratio combined with the 50mm objective lens provides bright image resolution during early morning or late evening shooting sessions. Therefore, marksmen obtain repeatable turret tracking, fast target engagement, and supreme optical clarity in demanding shooting environments.

Compatibility & Requirements

• Platform Compatibility: Mounts directly to standard 30mm scope rings or 30mm 1-piece cantilever optic mounts on bolt-action precision rifles, AR-10 platforms, and tactical MSRs.

• Power Requirements: Reticle illumination system operates on one CR2032 3V lithium coin battery.

• Usage Restrictions: Tailored specifically for long-range precision marksmanship, PRS competition, tactical target training, and big-game hunting.

• Maintenance: Clean optical glass using specialized microfiber cloths and non-abrasive lens cleaner; remove the CR2032 battery during long-term storage.

Pros & Limitations

Pros:

• First Focal Plane (FFP) MRAD Reticle: Subtensions and hash marks remain accurate at all magnification levels.

• Side Focus (SF) Parallax Adjustment: Side dial allows easy parallax correction without changing shooting position.

• HDX Glass Optical System: ED glass eliminates chromatic aberration and delivers high image contrast.

• LockDown Zero System: Resettable zero-stop turrets ensure an immediate, exact return to zero after dialing elevation.

Limitations:

• 30mm Mount Requirement: Requires standard 30mm mounting rings or cantilever mount.

• FFP Reticle Scaling: Crosshairs appear fine at 6x magnification and grow larger at 24x (inherent to all FFP optics).

Frequently Asked Questions (FAQs)

Q: What does “SF” stand for in the Sig Sauer TANGO4 6-24×50 SF MRAD scope?

A: “SF” stands for Side Focus. This side-mounted parallax adjustment knob allows you to quickly adjust parallax focus from 10 yards to infinity without reaching to the front objective bell.

Q: Is the Sig Sauer TANGO4 6-24×50 SF MRAD a First Focal Plane scope?

A: Yes! The TANGO4 6-24×50 features a First Focal Plane (FFP) reticle, ensuring that all MRAD reticle holdover subtensions remain true at all zoom settings.

Q: Does the reticle remain visible if the battery runs out?

A: Yes! The MRAD reticle is glass-etched, meaning it displays as a clear black reticle when the illumination is turned off or if the CR2032 battery is depleted.
