Feyachi Flip Up Rear Front and Iron Sights Backup for Picatinny

In this review the Feyachi Flip Up Rear Front and Iron Sights are assessed for shooters who need reliable backup sights that do not interfere with an optical optic. The bottom line is straightforward: these sights offer a compact, lightweight paired solution engineered for rapid transitions between optics and iron sights, making them a practical choice for range, competition, and defensive setups where a clean sight picture and fast target acquisition matter. The review focuses on build, deployment speed, and adjustment features that matter in use.

Key Features

• Machined aluminum construction: The lightweight but durable body reduces weight on the rail while standing up to regular field use.
• Mil-Spec hard anodized finish: The rigid coating improves corrosion resistance and wear life for long-term reliability.
• Calibrated paired set: The front and rear are matched and set to the same plane to simplify zeroing and maintain alignment under recoil.
• Flip-up spring load design: The push-button deployment allows quick, one-handed deployment when the optic is not usable.
• Adjustable windage and elevation: The rear offers MOA-style micro windage adjustment while the front provides elevation via an A2 post for fine-tuning point of impact.

Who It's For

These iron sights suit shooters mounting an optical sight on a Picatinny or Weaver rail who still want immediate, reliable backup iron sights. They are a good fit for competition shooters, tactical trainers, and recreational shooters who perform rapid transitions between longer-range optics and close-quarter aiming without removing hands from the weapon.

Those who should look elsewhere include users who require factory-matched integrated sight systems from a firearm maker or those who want included adjustment tools out of the box; the front sight elevation requires a separate A2 front sight adjustment tool if fine tuning is needed.

Pros & Cons

Pros

• Well machined from aluminum with a hard anodized finish, offering a durable, low-weight backup solution.
• Flip-up, spring-loaded push-button design provides fast and consistent deployment under stress.
• Calibrated and set as a matched pair so alignment and sight plane consistency are improved after installation.
• Micro windage adjustment on the rear and A2 post elevation on the front allow precise zeroing once tools are available.

Cons

• Adjustment tool for the front A2 post is not included, requiring a separate purchase for elevation changes.
• Offset RTS position may require practice for some shooters to master smooth transitions if they are accustomed to co-witnessed sights.

Frequently Asked Questions

Will these sights fit my Picatinny rail?
Yes, they are designed to attach to both Picatinny and Weaver rails and clamp to standard rail widths.

Are adjustment tools included?
The front sight elevation tool is not included, so you will need a separate A2 front sight adjustment tool to change elevation.

Do the sights co-witness with optics?
They are offset Rapid Transition Sights intended to be used in an offset position for quick canting transitions rather than traditional co-witness over an optic.
