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

Clear Product Overview

The Sig Sauer TANGO4 6-24x50mm 30mm FFP Riflescope (Illuminated DEV-L MRAD) is an advanced long-range optical system engineered for Precision Rifle Series (PRS) matches, tactical long-range target shooting, and long-range hunting applications. Produced by Sig Sauer Electro-Optics, this First Focal Plane (FFP) optic pairs high-magnification $6\text{x}-24\text{x}$ optical clarity with a 50mm objective lens and Sig Sauer’s DEV-L MRAD precision holdover grid reticle.

First, the TANGO4 6-24×50 incorporates Sig Sauer’s HDX glass optical system combining extra-low dispersion (ED) glass with high-transmittance glass. Consequently, marksmen experience sharp edge-to-edge resolution, vivid contrast, and maximum light transmission when spotting downrange targets across extreme distances. In addition, its First Focal Plane (FFP) design ensures that all reticle subtensions, windage dots, and elevation holdovers remain perfectly scaled and true across the entire $6\text{x}$ to $24\text{x}$ magnification range. Furthermore, the tactical elevation turret features Sig Sauer’s LockDown Zero System for fast, repeatable zero stops, while MOTAC (Motion Activated Illumination) technology automatically powers up the illuminated DEV-L reticle upon movement and turns off when static to preserve battery life. Therefore, it delivers exceptional long-range precision, mechanical turret tracking repeatability, and tactical durability.

Real-World Use Information

Long-range precision marksmen and PRS shooters choose the Sig Sauer Tango4 6-24×50 MRAD for bolt-action precision chassis rifles (such as 6.5 Creedmoor, 6mm GT, or .308 Win) and AR-10 DMR setups. Consequently, operators engaged in rapid-fire target strings can hold elevation and windage accurately directly on the DEV-L MRAD Christmas-tree reticle without needing to dial turrets.

Additionally, the $6\text{x}$ to $24\text{x}$ zoom range paired with the 50mm HDX objective lens provides clear target identification and mirage management at 1,000+ yards. Therefore, shooters obtain repeatable tracking consistency and instant sight alignment across variable target distances.

Compatibility & Requirements

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

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

• Usage Restrictions: Tailored specifically for long-range precision shooting, tactical target drills, PRS competition, and long-distance hunting.

• Maintenance: Clean optical lenses with microfiber glass cloths and specialized optic lens cleaner; remove the battery during long-term storage.

Pros & Limitations

Pros:

• First Focal Plane (FFP) DEV-L Reticle: Subtensions and MRAD holdover grid remain accurate at every magnification setting.

• HDX Glass Optical System: ED glass delivers bright, high-contrast images and eliminates chromatic aberration.

• LockDown Zero System: Resettable zero-stop turrets ensure quick return to zero after dialing elevation adjustments.

• MOTAC Motion Sensor: Automatically powers reticle illumination on with movement and off during inactivity.

Limitations:

• 30mm Ring Requirement: Requires 30mm scope rings or 30mm optic mount.

• FFP Reticle Size: Reticle appears fine at 6x and expands at 24x (characteristic of all FFP optics).

Frequently Asked Questions (FAQs)

Q: Is the Sig Sauer TANGO4 6-24×50 a First Focal Plane (FFP) or Second Focal Plane (SFP) scope?

A: The TANGO4 6-24×50 features a First Focal Plane (FFP) reticle layout, meaning the reticle holds true MRAD values at all magnification levels.

Q: What is the benefit of the DEV-L MRAD reticle?

A: The DEV-L MRAD reticle features a grid-style holdover pattern (“Christmas tree”) that allows shooters to rapidly hold for both elevation drop and wind drift without dialing turrets.

Q: Does the Sig Sauer TANGO4 have a zero stop?

A: Yes! The TANGO4 utilizes Sig Sauer’s LockDown Zero System turrets, providing a solid, repeatable mechanical zero stop.
