HD101 Tactical Reflex Red Dot Sight

HD101 Tactical Reflex Red Dot Sight

The HD101 Tactical Reflex Red Dot Sight is a high-performance optic designed for airsoft replicas and training platforms, offering fast target acquisition, wide field of view, and reliable performance in both CQB and outdoor environments.

Built around a large 22 × 33 mm reflex aperture, the HD101 delivers a full, unobstructed sight picture with a field of view of 15.8 meters at 100 meters, allowing rapid target transitions and superior situational awareness. The 1× magnification and unlimited eye relief make it ideal for dynamic airsoft gameplay where speed and accuracy matter most.

The sight features 4 selectable red reticle patterns (Starburst, Cross, Bullseye, and Dot) with 7 adjustable brightness levels, easily controlled via intuitive dual-button operation. Press the “+” button to power on the optic, and press “+” and “–” together to power it off. An auto shut-off function activates after approximately 2 hours of inactivity, helping preserve battery life during extended use.

Powered by an integrated USB Type-C rechargeable battery, the HD101 requires only 30 minutes of charging to deliver up to 240 hours of runtime, eliminating the need for disposable batteries and ensuring consistent performance between games.

Constructed from aerospace-grade aluminum alloy, the HD101 is waterproof, fog-proof, and shock-resistant, built to withstand demanding airsoft conditions and repeated use. Windage and elevation adjustments (±35 MOA, 1 MOA per click) allow precise zeroing, with adjustment tools included.

Compatible with 20mm Picatinny / Weaver rails, the HD101 mounts securely and can be quickly reinstalled when needed, making it a dependable and versatile optic for any airsoft loadout.
