SIG SAUER KILO3K 6x22mm BDX Rangefinder – Ranger Green

The SIG SAUER KILO3K 6x22mm rangefinder combines a compact monocular format with five ranging modes, a red OLED display, onboard environmental sensing, Bluetooth connectivity, and SIG’s BDX-U and BDX-X ballistic capabilities. Finished in OD green and black, it is designed for hunters, recreational shooters, archers, and field users who want more than a basic line-of-sight distance reading. This exact model is manufacturer part number SOK3K602, UPC 798681661589.

6x22mm Monocular Format

The KILO3K uses 6x magnification and a 22mm objective in a handheld monocular layout. Six-power magnification gives the user a closer view of distant terrain and targets while remaining practical for handheld observation. The protected product specifications list 18mm of eye relief and a circle reticle. Its OD green and black housing provides a field-oriented appearance without adding unnecessary complexity to the controls.

Five Ranging Modes

SIG SAUER identifies five operating modes for the KILO3K: Line of Sight, Angle Modified Range, Archery, BDX-U, and BDX-X. Line-of-Sight mode reports direct distance, while Angle Modified Range accounts for the shooting angle to provide a more useful equivalent range. Archery mode supports bowhunting applications, and the BDX modes add ballistic calculation and connected-device functions.

The correct mode depends on the equipment, environment, and intended use. Users should become familiar with the display and menu system before entering the field, verify all profile information, and treat calculated solutions as aids rather than substitutes for sound judgment and confirmed data.

Applied Ballistics Ultralight

In BDX-U mode, the KILO3K uses an embedded Applied Ballistics Ultralight engine with a bullet database and support for G1 and G7 drag curves. The rangefinder can combine a stored ballistic profile with measured environmental parameters to calculate windage and elevation solutions in MOA or MIL units. Those solutions are shown in the rangefinder display for convenient field reference.

Ballistic output depends on the accuracy of the ammunition, firearm, sight height, muzzle velocity, zero, atmosphere, and other profile inputs. Owners should confirm their actual equipment data and validate predicted solutions at known distances whenever possible.

Bluetooth and BDX Integration

Bluetooth connectivity allows the KILO3K to work with the SIG BDX ecosystem. SIG states that ranging and ballistic information can be communicated to a paired compatible BDX sight so the system can provide an illuminated holdover reference. The unit is also compatible with the BDX smartphone application for profile setup and advanced configuration.

Connected operation requires compatible equipment and correct pairing. App availability, mobile operating-system support, firmware, and device compatibility can change over time, so current SIG documentation should be reviewed before purchase or setup.

Red OLED Display and Environmental Sensors

The red OLED display presents ranging information in the user’s field of view. Integrated environmental sensors support the ballistic modes by measuring relevant conditions in real time. Display brightness and ranging behavior should be configured for the anticipated light and terrain conditions before field use.

Field Use and Care

Read the current SIG SAUER instructions before use, install the specified battery correctly, and confirm settings before entering the field. Keep the optical surfaces clean with appropriate lens-care materials and protect the unit from unnecessary impact or prolonged exposure to extreme conditions. Never look directly into a laser emitter or use optical instruments to view the emitted beam. Confirm all readings and remain aware of the target area and surroundings.
