Pulsar Thermal Front Attachments for Turning Your Day Scope into Thermal
Pulsar thermal front attachments allow shooters to add thermal imaging capability to an existing daytime riflescope without replacing familiar glass, mounts, or shooting ergonomics. Mounted in front of a traditional optic, these clip-on systems convert a day scope into a thermal sight—ideal for hog hunting, predator control, and nighttime property work where heat detection matters.
If you prefer a dedicated all-in-one solution, explore our thermal riflescopes. For handheld scanning before you ever shoulder a rifle, see our thermal monoculars. To keep everything powered through long nights, browse batteries & power packs.
Buyer’s Guide: Choosing the Right Thermal Front Attachment
The Krypton 2 line is designed for shooters who want thermal performance without reconfiguring their rifle. Choosing between models comes down to detection range, terrain, and how much detail you need at distance.
Sensor Resolution
Krypton 2 XG50 uses a 640×480 thermal sensor, delivering stronger detail recognition at longer distances. Krypton 2 XQ35 uses a 384×288 sensor that keeps the system compact and efficient for typical night-hunting ranges.
Objective Lens and Detection Distance
The XG50 features a 50mm germanium objective and is rated for detection out to 2,500 yards. The XQ35 uses a 35mm objective and offers detection out to 1,400 yards, well suited to mixed cover and shorter sight lines.
Battery Runtime and Power Options
Both Krypton 2 models run on the included IPS7 Li-Ion battery pack, providing up to 11 hours of runtime. USB-C external power support allows extended operation using a power bank for overnight hunts or long surveillance sessions.
Mounting and Day Scope Compatibility
Thermal front attachments mount ahead of your existing day scope. For best results, most shooters keep their optic at low to moderate magnification, preserving image clarity and maintaining a familiar shooting experience.

Functions of Thermal Attachments
Thermal front attachments exist to do one thing well: add thermal capability to a rifle you already trust. They preserve zero, maintain familiar ergonomics, and let one rifle serve both daytime and nighttime roles.
- Convert a standard day scope into a thermal sight
- Detect heat signatures in darkness without visible light
- Maintain point-of-impact consistency when mounted correctly
- Record footage and transfer files wirelessly
- Operate reliably in rain, cold, and rough field conditions
