About Sig Sauer Rifle Scopes

Sig Sauer produces a broad lineup of rifle scopes designed for MSR/AR platforms, bolt-action rifles, and everything in between. Whether you're shooting at the range, pursuing game in the field, or running a precision long-range setup, Sig Sauer offers a scope built for the application. All Sig Sauer scopes are backed by the SIG SAUER Infinite Guarantee, a fully transferable, no-receipt-required lifetime warranty that covers the optic for as long as you own it.

The Sig Sauer riflescope catalog spans multiple distinct product families, each designed with a specific use case in mind. Understanding the differences between them makes it easier to find the right scope for your platform and purpose.

The TANGO Series

The TANGO lineup is Sig Sauer's largest riflescope family and covers everything from entry-level LPVOs to military-grade precision glass.

The TANGO-SPR (Special Purpose Rifle) is the most accessible option in the TANGO lineup. It features a high-performance 4:1 optical system with low dispersion glass, an exposed zero-stop elevation dial, dedicated side focus, lay-flat flip-back lens covers, and a factory-installed SPR mount included in the box. The TANGO-SPR is available in 1-4x24mm, 4-16x44mm, and 6-24x52mm configurations, covering a range of magnification needs at a price point that suits a wide audience.

The TANGO-MSR is purpose-built for modern sporting rifles and is available in several configurations spanning 1-6x, 1-8x, 1-10x, 2-12x, and 5-30x magnification ranges. All TANGO-MSR models feature low dispersion glass, an integrated throw lever for fast magnification changes, an illuminated reticle, and waterproof, shockproof, and fogproof construction. The TANGO-MSR Compact series condenses that performance into a smaller, lighter package for shooters who prioritize weight.

The TANGO-DMR (Designated Marksman Rifle) steps up to a more demanding performance tier, available in 3-18x44mm and 5-30x56mm configurations. It features a military-inspired locking illumination control, an exposed multi-lock elevation dial with zero stop, a first focal plane reticle, and reticle options in MOA or MRAD. The TANGO-DMR is designed for precision applications that demand consistent adjustments and dependable tracking.

At the top of the TANGO lineup, the TANGO6T is selected by the U.S. Army for both the Squad Designated Marksman Rifle System and U.S. Special Forces. It is assembled in Sig Sauer's optics factory in Wilsonville, Oregon. The TANGO6T is built around the HDX optical system, which pairs extra-low dispersion glass with high transmittance glass for industry-leading light transmission and optical clarity. It offers a 1-6x24mm magnification range, is available in first or second focal plane designs, features night vision-compatible illumination settings, and is rated to IPX-8 for waterproofing. Multiple reticle options are available, including the DWLR6, 5.56/7.62 Horseshoe Dot, Hellfire M855A1, FL-6 Hellfire, and others.

The WHISKEY Series

The WHISKEY series is built for hunting and general-purpose use. The WHISKEY4 is available in 2.5-10x42mm, 5-20x50mm, 4-16x44mm and 3-12x44mm configurations in both illuminated and non-illuminated versions. The WHISKEY6 runs 3-18x44mm and supports multi-lock zero stop for repeatable adjustments in the field. Depending on the model, these hunting lines feature either SIG Sauer's illuminated Hellfire system or ultra-lightweight, high-contrast traditional glass reticles designed to handle demanding field conditions.

The SIERRA BDX Series

The SIERRA series integrates with Sig Sauer's BDX (Ballistic Data Xchange) technology. BDX-compatible scopes link wirelessly with compatible Sig Sauer rangefinders to automatically illuminate the correct holdover point in the reticle based on the measured range to the target. The SIERRA4 BDX and SIERRA6 BDX cover magnification ranges from 2-12x40mm through 5-30x56mm. These scopes are designed for hunters and shooters who want a connected, data-driven system across their optics.

The BUCKMASTERS Series

The BUCKMASTERS line offers illuminated second focal plane scopes in 3-9x40mm, 3-9x50mm, and 3-12x44mm configurations. These are straightforward hunting scopes with the Hellfire Illuminated Buckmasters BDC reticle, designed to be accessible, reliable glass for deer hunters and general field use.

Who Are Sig Sauer Rifle Scopes For?

Sig Sauer's lineup covers a wide range of shooters. The TANGO-SPR and BUCKMASTERS series are solid choices for hunters and range shooters who want reliable performance without a premium price tag. The TANGO-MSR is a strong match for AR-platform shooters who want capable glass with solid tracking and illuminated reticle options. The TANGO-DMR suits precision rifle shooters who need refined long-range adjustability. The WHISKEY series fits hunters who want durable, field-proven scopes, and the SIERRA BDX family serves shooters who want integrated ballistic solutions across their optics and rangefinder.
