Burris FastFire E Red Dot Sight 3.5 MOA Dot

Burris FastFire E Enclosed Reflex Sight

The Burris FastFire E brings the proven FastFire concept into a fully enclosed emitter design built for pistols, shotguns, carbines, hunting, competition, and duty applications. Its rugged 7075 aluminum housing protects the enclosed emitter from the mud, snow, rain, and debris that can obstruct an open-emitter red dot. The result is a compact enclosed red dot sight designed for dependable performance when conditions are less than ideal.

A 3.5 MOA dot provides a useful balance between rapid target acquisition and aiming precision. The FastFire E operates at 1x magnification and uses a wide 22x17mm viewing window, making it well suited to fast, both-eyes-open shooting. The aspherical lenses provide a distortion-free, glare-resistant sight picture, while eight illumination settings—including two night-vision-compatible settings—allow the dot to be adapted to different lighting conditions.

Enclosed Emitter Protection

The biggest advantage of the FastFire E over an open-emitter reflex sight is the enclosed optical design. By surrounding the emitter, the housing helps prevent environmental obstructions from interfering with the aiming point. The waterproof, shockproof, and fogproof construction makes the FastFire E a practical choice for hunting and defensive or duty applications where reliability in adverse weather matters.

Always-On 3.5 MOA Dot

The FastFire E is designed for immediate readiness with an always-on 3.5 MOA dot and up to 60,000 hours of battery life from a single CR2032 lithium battery. A side-mounted battery compartment allows the battery to be changed without removing the optic from its mounting position, helping maintain zero. Brightness lock and button lockout features also help prevent unintended changes to the sight's settings.

FastFire E Mounting and Adjustment

The Burris FastFire E uses the Aimpoint ACRO footprint, giving shooters access to a broad selection of compatible mounting solutions. Windage and elevation are fully adjustable with 100 MOA of total adjustment capability and 1 MOA adjustment increments. A secure clamp system and included T10 tool make installation and adjustment straightforward.

Red or Green 3.5 MOA Reticle

The FastFire E is available with either a 3.5 MOA red dot or 3.5 MOA green dot. The red-dot model is item #300266, while the green-dot model is item #300267. Both versions use the same enclosed housing and optical system, allowing you to select the reticle color that provides the best contrast and visibility for your eyes and shooting environment.

Compact Enclosed Red Dot for Pistols, Shotguns and Carbines

At approximately 2.45 ounces and only 1.81 inches long, the FastFire E provides enclosed-emitter protection without adding excessive bulk. Its combination of rugged construction, long battery life, wide viewing window, automatic brightness reset, and ACRO footprint makes it a versatile red dot sight for pistols, shotguns, and carbines.
