Experience precision, speed, and reliability in a compact form with the Alpen Argus LT Sub-Compact Open Red Dot Sight. Designed for shooters who demand instant target acquisition and dependable accuracy, the Argus LT pairs rugged engineering with advanced optical technology — delivering performance far beyond its size. The open reflex 1×26×23 mm lens offers an exceptionally wide and clear field of view, making it easy to maintain situational awareness while tracking fast-moving targets. With three reticle options — 3 MOA dot, circle, or circle-with-dot — you can adapt your sight picture for precision shooting or rapid close-range engagement. Each reticle is crisp, daylight-bright, and easily visible in any environment. Built from CNC-machined 6061-T6 aluminum, the Argus LT is waterproof (IPX7), fog-proof, and recoil-rated to handle the toughest conditions in the field or on the range. The housing is nitrogen-filled to prevent internal fogging and fully sealed to protect against moisture, dust, and debris. Equipped with DynamicDot motion-sensor technology, the sight automatically powers on when movement is detected and conserves energy when stationary, extending battery life up to thousands of hours. Precision 0.3 MRAD click adjustments allow fine windage and elevation tuning, ensuring reliable zero retention even under heavy use. Compatible with RMR or Picatinny footprints, the Alpen Argus LT Sub-Compact is ideal for pistols, AR platforms, or any setup requiring a lightweight, low-profile sight. Whether for tactical use, competition, or hunting, this optic delivers the perfect balance of clarity, speed, and durability — all backed by Alpen's reputation for exceptional optical performance.
