Firefield Impact Mini Reflex Sight 1x16x21 - 5 MOA Red Dot, Black

The Firefield Impact Mini Reflex Sight brings compact, fast-acquisition red dot performance to tactical pistols, shotguns, and modern sporting rifles. This 1x16x21 reflex sight pairs a simple 5 MOA illuminated red dot with genuine ruggedness in a form factor light enough to cowitness on most platforms. At just 1 ounce, it won't bog down your carry gun or throw off your balance—and the infinite eye relief means your sight picture stays true no matter how you hold it. Built from 6061-T6 aircraft-grade aluminum and finished in black anodize, the Impact Mini is shaped to handle hard use without complaint.

Close-quarters work demands reliable, bright reticles under variable light. This sight offers five brightness levels, tuned to cut through glare or punch through dark cover. The AR red-coated glass stays crisp across its 50-yard parallax setting, so target engagement stays snappy from retention distance out to intermediate range. IP55 weatherproofing and shockproof construction mean it'll take the bumps and weather your kit actually encounters—not theoretical durability, real-world abuse tolerance.

Setup is straightforward: the sight mounts to any Weaver or Picatinny rail, and Firefield includes both low-profile and cowitness mounts in the box, so you can dial in your preferred sight picture without shopping for adapters. Elevation and windage both offer 120 MOA of adjustment for zeroing, and a single CR1632 battery runs up to 40 hours on high or 200 on low—meaning you're not swapping batteries constantly. The package includes the battery, a lens cover, and adjustment tools, so you can be ready to shoot out of the bag.

Frequently Asked Questions

What guns will this reflex sight mount on?

The Firefield Impact Mini uses Weaver and Picatinny rail mounts, so it'll work on any modern rifle, shotgun, or pistol with either mount type. The kit includes both low-profile and cowitness mounts, so you can pick the height that works best for your platform.

How bright is the red dot, and can I use it in daylight?

Five brightness levels let you dial the reticle brightness to match your environment, from indoor low-light work to bright outdoor use. The AR red-coated glass helps the dot stand out without washing out in daylight.

How long does the battery last?

A single CR1632 battery provides up to 40 hours of runtime on the highest brightness setting, or up to 200 hours on the lowest setting. Firefield includes a battery and adjustment tools in the box so you're ready to mount and zero out of the package.

What's the field of view, and is the sight fogproof?

The sight delivers infinite eye relief and a crystal-clear field of view across its 50-yard parallax setting. It is not filled with nitrogen and is not fog-proof, but it carries an IP55 waterproof rating for rain and splash protection.
