Sig Sauer Electro-Optics Foxtrot2 Tactical Weapon Light - Black Anodized (SOF2R100)

The Sig Sauer Foxtrot2 tactical weapon light is a compact, rechargeable mounted light built for pistols and modern carbines that demand serious illumination without bulk. Throwing 700 lumens and 20,000 candela, the Foxtrot2 produces a bright, concentrated beam tight enough for precise target identification at distance, yet wide enough to illuminate your entire work area when you need situational awareness. Whether you're running drills at the range, mounting it on a duty gun, or setting up a modern sporting rifle for low-light scenarios, this is the kind of tool that earns its real estate on your rail.

What sets the Foxtrot2 apart is its FlexCore battery system. You get a rechargeable 16340 battery in the box, but the light runs just as well on standard CR123A cells—so you're never stuck if you're traveling, training in remote locations, or simply prefer the reliability of common disposables. Runtime stretches to 1.5 hours on a full charge, enough for extended range sessions or serious training blocks. The IPX7 rating means it'll handle weather, sweat, and the occasional splash without flinching.

The ambidextrous paddle switches are the real standout for tactical work. You get momentary activation for quick target checks, latching mode for sustained illumination, and a threshold mode that lets you fine-tune your activation preference. The light ships with two rail interface inserts—one M1913 (Picatinny) for modern tactical rifles and standard rails, and one for Sig's proprietary pistol mounting systems—so you can set it up on your specific platform right out of the box. The 4-position sliding insert gives you fine-tuned positioning for your grip and sight picture.

Compatible with the majority of modern Sig handguns (full-size and compact P320 variants, P226, P229, P220, and 1911 frames with rails), as well as Sig's MCX, MPX, and 5xx-series rifles, the Foxtrot2 is engineered for Sig's ecosystem but built tough enough to earn a place in any serious shooter's kit.

Frequently Asked Questions

Will the Foxtrot2 fit my Sig P365 or P365X?

No. The Foxtrot2 is compatible with full-size and compact P320 variants, P365-XMACRO, P365-AXG, P226, P229, P220, SP2022, and 1911 frames with rails, but not the standard P365, P365X, or P365XL. Always verify your specific pistol model before purchasing.

Can I use regular CR123A batteries instead of the rechargeable one?

Yes. The FlexCore system runs on either the included rechargeable 16340 or standard CR123A primary batteries, so you can swap to common disposables anytime you need them.

What comes in the box with the Foxtrot2?

The light ships with a rechargeable 16340 battery and two rail interface inserts—one M1913 (Picatinny) insert for modern tactical rifles, and one insert designed for Sig's proprietary pistol rail systems.

Is this light suitable for carbine mounting?

Yes. With the M1913 Picatinny insert included, the Foxtrot2 mounts on modern sporting rifles and carbines equipped with standard tactical rails, including Sig's MCX, MPX, and 5xx-series rifles.
