Reflex Sight with Multiple Reticles Red Dot - Tubeless 40mm Lens

In this review the Feyachi Reflex Sight with a tubeless 40 mm lens is assessed for shooters who want a compact, lightweight red dot that prioritizes quick target acquisition and a wide field of view. The single biggest reason to consider this sight is its combination of a larger reflex aperture and a multiple-reticle system, which makes aiming faster and more flexible for casual range sessions, hunting setups and basic tactical use. The review focuses on real-world use, battery life considerations and mechanical fit to standard 20 mm Picatinny rails.

Key Features

• Tubeless 40 mm lens: The larger aperture provides a wider field of view and faster target acquisition at close to mid ranges.
• Multiple reticle options: Four selectable reticles let the shooter choose the aiming pattern that matches their preference or task.
• Six brightness settings: Adjustable brightness helps keep the dot usable from low light to brighter conditions while conserving battery when dimmed.
• Integrated Picatinny mount: A built-in mount for standard 20 mm Picatinny rails installs securely and is made to resist loosening under normal use.
• Parallax corrected: The sight offers unlimited eye relief and parallax correction so the point of aim remains consistent with changes in head position.
• Aluminum alloy construction: The housing balances durability and low weight for easy handling and carry.

Who It's For

The sight is best for hobby shooters, hunters on a budget and anyone who needs a simple, lightweight red dot for close to mid-range engagement. Its quick acquisition and larger lens suit driving fast target transitions and maintaining situational awareness in field use.

Those who need ultra-high reticle clarity for bright daylight long-range precision or military-grade guaranteed longevity should look at higher-end optics; some users report mixed durability and inconsistent reticle visibility in very bright sun, so serious competitive shooters may prefer a more robust option.
