Apex LRF 50mm Mounted Thermal Riflescope
Description
The Alpen Optics Apex LRF 50mm Mounted Thermal Riflescope is a professional-grade rifle-mounted thermal optic built for hunters and tactical shooters who demand performance in the most challenging conditions. Whether you're pursuing predators in complete darkness or tracking targets through dense foliage, this optic lets you detect heat signatures at distances up to 2600 meters - giving you a decisive edge when visibility fails. At its core is a 640x512, 12 µm pixel pitch thermal sensor with sensitivity rated at less than 20 mK, delivering razor-sharp thermal imaging with outstanding detail.
Integrated directly into the optic is a laser rangefinder capable of precise measurements out to 1000 meters, so you can range and engage targets without breaking your setup or reaching for a separate device. The high-contrast OLED display renders vivid imagery in six selectable color palettes, while multiple reticle patterns and five zeroing profiles keep you dialed in shot after shot. Built for the demands of field use, this riflescope is waterproof, shockproof, and engineered to hold up to the rigors of recoil-heavy platforms including the AR.
Key Features
- 640x512 Thermal Sensor (12 µm, <20 mK NETD): Industry-leading thermal sensitivity detects the slightest temperature differences for crisp, detailed heat signature imaging.
- 2600m Detection Range: The 50mm objective lens extends detection distance to an impressive 2600 meters - ideal for long-range predator hunting and open-country surveillance.
- Integrated Laser Rangefinder (LRF up to 1000m): Built-in LRF delivers precise distance measurements without the need for a separate rangefinder device.
- OLED Display (1440x1080): High-contrast OLED screen produces vivid, sharp imagery in six color palettes - black hot, white hot, green, iron hot, red hot, and sepia.
- Digital Magnification (1x, 2x, 4x, 8x): Four magnification levels give you the flexibility to scan wide or zoom in on distant targets.
- Multiple Reticle Styles and Colors with 5 Zeroing Profiles: Fully customizable reticle options and five independent zeroing profiles support precision shooting across multiple loads or firearms.
- Recoil-Activated Video Recording with 32GB Internal Storage: Automatically records footage on firing, capturing every hunt or engagement without manual intervention.
- Built-In Wi-Fi: Stream live thermal video to your phone or device for real-time sharing or remote monitoring in the field.
- Dual Rechargeable Battery System (up to 15 hours): Two 18650 rechargeable batteries provide extended runtime to keep you operational through long nights in the field.
- Waterproof and Shockproof Construction: Rugged housing withstands demanding field environments and the repeated recoil of rifle-mounted use.
Objective Lens Options & Which to Choose
- 35mm Objective: A more compact and lightweight option with detection range up to 1800 meters. Best for hunters and shooters who need a nimble, easy-to-mount thermal at shorter to mid-range distances, or who prioritize a lower-profile setup on their rifle.
- 50mm Objective: The longer-range performer with detection capability out to 2600 meters. The right choice for open-country hunters, predator callers, and tactical shooters who need maximum reach and the ability to identify targets at extreme distances.

FAQ
Is the Apex LRF 50mm compatible with AR-platform rifles?
Yes - the Apex LRF Thermal Riflescope is particularly well-suited for the AR platform. It mounts directly to the rifle and is built to handle repeated recoil, with recoil-activated video recording that triggers automatically when you fire.
What is the difference between the 35mm and 50mm models?
The primary difference is detection range and objective lens size. The 35mm model detects targets at up to 1800 meters and offers a more compact profile, while the 50mm model extends detection to 2600 meters, making it the better choice for long-range applications in open terrain.
How long do the batteries last, and can I recharge them in the field?
The dual rechargeable 18650 battery system provides up to 15 hours of runtime. The 18650 format is widely used, and spare or replacement batteries are easy to find. Having two batteries in the system also gives you flexibility to swap cells in the field if needed.
Can I stream live video from the scope to my phone?
Yes. The Apex LRF 50mm has built-in Wi-Fi that allows you to stream live thermal video directly to your smartphone or other compatible device, making it useful for real-time sharing, remote monitoring, or reviewing footage after a hunt.
Does the laser rangefinder work independently of the thermal imaging?
The laser rangefinder is integrated into the same unit and works in tandem with the thermal imaging system. You can range targets detected thermally out to 1000 meters without needing a separate device, keeping your gear setup clean and efficient.
Is this scope waterproof? Can I use it in rain or wet conditions?
Yes. The Apex LRF 50mm Mounted Thermal Riflescope features waterproof and shockproof construction, making it suitable for use in rain, wet brush, and other demanding field environments.
