The Alpen Argus LT 1x20 is an enclosed-emitter red dot with integrated solar charging — the sight pulls power from its top-mounted solar panel whenever ambient light allows, falling back to a CR1632 only in low light. The sealed emitter housing keeps dust, lint, and rain off the LED, and a 10-level brightness range (8 daytime + 2 NVG) covers use from bright sun to night-vision pairing.

Key Features

• Enclosed emitter — sealed optical path protects the LED from weather, debris, and glare bloom
• Solar + CR1632 hybrid power — up to 50,000 hours of runtime; sight runs on solar alone in bright conditions
• Three switchable reticles — 3 MOA dot, circle, or circle-with-dot
• 10 illumination levels including 2 night-vision-compatible settings
• ACRO footprint for direct mounting on pistols and adapter plates
• DynamicDot motion wake — sight goes to standby after 2 minutes idle, instant-on when moved
• Waterproof to 1 m / 30 min
• Compact 46 × 36 × 34 mm, 110 g aluminum chassis

Ideal For

• Duty and carry pistol users on ACRO-cut slides who want an enclosed emitter for weather and grit resistance
• Night-vision shooters needing the 2 low-brightness NVG settings
• Competition shooters who can't afford dead batteries between stages — solar keeps the dot alive all day
