20mm Tube 3 MOA Red Dot 5 Brightness Levels Polymer Housing Picatinny / Weaver

Overview

The Valken RDA20 Mini Red Dot Sight is a compact, low-profile optic built for airsoft players who want a simple, lightweight aiming solution. Its 20mm tube diameter keeps the footprint small, making it ideal for pistols, SMGs, and minimal rifle setups where weight and balance matter.

Reticle & Illumination

The RDA20 features a 3 MOA center red dot optimized for close-quarters engagements. Powered by a CR1620 lithium battery, the optic offers five brightness settings to maintain visibility across indoor CQB arenas and outdoor fields. A phase-coated lens enhances clarity and preserves true color for a clean sight picture.

Construction & Mounting

Built with a nylon fiber–reinforced, weather-resistant polymer housing, the RDA20 balances durability with low weight. It mounts securely to most 20mm Picatinny and Weaver rails, making it compatible with a wide range of airsoft platforms.
