Feyachi 3X Magnifier & RS-30 Reflex Red Dot Sight Combo — Black, Flip-to-Side Mount, Lightweight Aluminum

The Feyachi M40 combo pairs a 3X flip-to-side magnifier with an RS-30 reflex red dot to extend effective range while preserving rapid target acquisition.

Designed for shooters who want a flexible aiming system, this kit combines a 3X magnifier and a compact reflex sight on Picatinny mounts. The magnifier flips out of the way for close-quarters use and snaps into place for mid-range engagement, while the red dot provides fast, both-eyes-open aiming. Built from hard-anodized aluminum, the set balances durability with low weight so it suits a variety of rifles and shooting scenarios.

How does this combo improve mid-range aiming?

The 3X magnifier amplifies the red dot to make distant targets easier to identify and place accurate shots without switching to a separate optic. Eye relief is maintained to keep a comfortable working distance and a broad field of view.

• 3X magnification for clearer target presentation at longer distances
• 2.4 inches of eye relief to reduce eye strain and speed acquisition
• Wide field of view so situational awareness is preserved
• Flip-to-side mount for instant transition between magnified and direct-view modes

What aiming options and adjustments are available?

The RS-30 reflex unit offers selectable reticle patterns and multiple brightness steps so you can adapt to changing light. Windage and elevation adjustments let you center the dot precisely, and the magnifier’s focus ring sharpens the view quickly.

• Four reticle patterns to match shooter preference and task
• Five brightness settings for varied lighting conditions
• Tool-free windage and elevation adjustments for on-plate zeroing
• Fast-focus eyepiece on the magnifier for quick clarity tweaks

Is the kit durable enough for field use?

Yes—components are machined from high-grade aluminum and finished with a hard-coat anodize that resists wear. The reflex and magnifier are engineered to handle recoil and routine handling without adding unnecessary weight to the rifle.

• Shockproof aluminum construction for reliable performance under recoil
• Hard-coat anodized finish for corrosion and abrasion resistance
• Lightweight design that minimizes added bulk to the firearm
• Secure Picatinny mounts for repeatable placement and co-witnessing

How does mounting and co-witnessing work with iron sights?

The RS-30 installs on a Picatinny rail and is compatible with absolute co-witness when paired with A2-style front sights. The magnifier uses a flip-to-side mount that aligns with the reflex to keep both systems working together smoothly.

• Picatinny-compatible reflex mount for standard rail systems
• Absolute co-witness with A2 front sight for consistent sight picture
• Flip-to-side magnifier maintains alignment when deployed or stowed
• Repeatable mounts reduce the need for re-zeroing after removal

Who this is for: the Feyachi M40 3X + RS-30 combo is aimed at recreational and practical shooters who want a single optic solution that covers close-quarters and mid-range tasks. It suits owners of modern sporting rifles, carbines, and patrol-style platforms who value quick target acquisition, simple day-to-day durability, and the convenience of a flip-to-side magnifier without carrying extra optics.
