Firefield Impact XL Reflex Sight Overview

By Suzanne Wiley

Reflex (red dot) sights always appear on the lists of the best AR-15 accessories to own. And for good reason. Adding very little weight to your rifle, reflex sights help you get on target quickly in high-stress situations.

There are many benefits to running a red dot on your AR or other MSR:

  • Accurate
  • Easy to use
  • Short learning curve
  • Affordable

Are Red Dot Sights Accurate?

Red dot and reflex sights are extremely accurate when used in self-defense, competition and tactical applications because the illuminated dot or reticle makes acquiring a target very quickly. Users do not have to close one eye or focus on two separate things to make a precise hit.

What is the Effective Range of a Red Dot Sight?

Reflex sights come in a variety of MOA dot sizes but all will be accurate up to at least 100 yards if sighted-in correctly.

These illuminated sights are popular for AR-15 and other MSR owners because the primary use of these types of rifles is when speed matters just as much as accuracy—predator hunting, target shooting, 3-Gun competition and self-defense.

For those looking for an affordable option, Firefield offers the full-sized Impact XL reflex sight with customizable reticle options.

Reflex sights are designed for close quarters but are accurate out to 100 yards at least.

Though the differences in reticles is primarily user preference, they do have their own unique benefits depending on what type of gun, shooting distance and target you use the reflex sight with.

3 MOA Dot

A 3 MOA dot is the sweet spot between having too much reticle covering your target and too little of a dot to acquire at further distances. This size dot is accurate for up-close work as well as mid ranges.

5 MOA Dot

This larger dot size is ultra quick to see in high-speed situations. It can also help those with poor or aging eyes and for those who have astigmatism.

Circle Dot

The circle dot reticle is useful for shotguns due to spread, as well as how much quicker it can be to see.

The Impact XL is a versatile reflex sight with multiple reticle options which transitions smoothly from AR to shotgun.
