Burris FastFire E 3.5 MOA Green Dot Sight Enclosed Emitter Aimpoint ACRO Footprint

The Burris FastFire E represents the first fully enclosed emitter red dot in the FastFire series, engineered specifically for pistols, shotguns, and carbines. Built from monolithic machined aluminum, the FastFire E is waterproof, shockproof, and fogproof-ready for any environment. The enclosed emitter design protects the LED from mud, snow, and debris that would compromise open emitter sights, ensuring flawless performance whether you're on the range, in the field, or on duty.The 3.5 MOA green dot with "always on" feature ensures instant readiness, powered by a CR2032 battery delivering 60,000-hour life. Aspherical lenses provide a distortion-free, glare-resistant view enhanced by eight brightness settings including two night vision compatible modes. The wide 22x17mm window and 1x magnification enable fast, both-eyes-open shooting with superior situational awareness. Fully adjustable windage and elevation with 100 MOA range and Aimpoint ACRO footprint ensure precise, secure mounting across multiple platforms.Fully Enclosed Emitter ProtectionThe FastFire E's defining feature is its fully enclosed emitter design-a first for the FastFire series. The monolithic machined housing completely protects the LED emitter from environmental contamination that renders open emitter sights inoperable. Mud, snow, debris, and moisture cannot reach the emitter, ensuring the sight maintains a clear dot regardless of conditions. This enclosed design delivers reliability that open emitter pistol dots cannot match in harsh environments.Monolithic 7075 Aluminum ConstructionCrafted from a single piece of 7075 aluminum through precision CNC machining, the FastFire E achieves superior strength and durability compared to multi-piece housings. The monolithic construction eliminates weak points from fasteners or joints, providing exceptional recoil resistance and protection against impact damage. This rugged build withstands the battering recoil of magnum pistols, shotgun slugs, and hard-use carbine applications.Waterproof, Shockproof, FogproofThe FastFire E performs flawlessly through rain, snow, mud, and extreme temperature swings. Fully waterproof sealing protects internal components from moisture ingress. Shockproof construction absorbs recoil and impact without losing zero or damaging electronics. Nitrogen-purged fogproof optics prevent internal fogging when moving between temperature extremes.Always-On 3.5 MOA Green DotThe "always on" feature ensures the FastFire E is ready for action without fumbling for power buttons in critical moments. The 3.5 MOA green dot provides an optimal balance between precision and visibility-small enough for accurate shot placement yet large enough for rapid acquisition. Green dot color offers superior visibility in certain lighting conditions and for shooters who prefer green over traditional red. The CR2032 battery delivers an impressive 60,000-hour runtime, minimizing battery changes and ensuring the sight remains operational through years of regular use.Side-Mounted Battery CompartmentBattery changes occur without removing the optic or losing zero. The side-mounted battery compartment provides quick access to swap batteries while the sight remains mounted and zeroed on the firearm. This design eliminates the frustration and time loss of re-zeroing after routine battery replacement.Aspherical Lenses for Distortion-Free ClarityAspherical lens design eliminates the spherical aberration found in conventional lenses, providing edge-to-edge clarity without distortion. The lenses also feature anti-glare coatings that reduce reflection and washout in bright sunlight or when shooting toward light sources. This optical quality ensures a clean, crisp sight picture in all lighting conditions.Eight Brightness Settings Including Night VisionEight brightness levels adapt the dot intensity to match ambient lighting conditions, from bright daylight to low-light environments. Two settings are compatible with night vision devices, enabling use with Gen I through Gen III+ night vision without blooming or washout that would compromise sight picture.Wide 22x17mm Viewing WindowThe expansive 22x17mm window provides a generous field of view that enhances speed and situational awareness. The large window makes dot acquisition faster and easier, particularly during dynamic shooting or target transitions. Shooters maintain better peripheral vision awareness compared to smaller optic windows.1x Magnification Parallax-Free DesignTrue 1x magnification with parallax-free design enables both-eyes-open shooting technique. This allows shooters to maintain full situational awareness with both eyes focused on the target while the dot appears superimposed. The result is faster target engagement and superior awareness of surroundings-critical advantages for defensive use.100 MOA Windage and Elevation AdjustmentFully adjustable windage and elevation with 100 MOA total adjustment range provides precise point-of-aim/point-of-impact alignment across multiple firearm platforms and ammunition types. Adjustments are tool-free and feature positive clicks for repeatable, precise zeroing.Aimpoint ACRO Footprint CompatibilityThe FastFire E uses the widely adopted Aimpoint ACRO footprint, ensuring compatibility with the extensive ecosystem of mounting plates, adapter plates, and pistol slides cut for ACRO pattern. The secure clamp mounting system with included T10 tool provides rock-solid attachment that maintains zero through heavy recoil.Brightness Lock and Button LockoutBrightness lock prevents accidental brightness changes during use. Button lockout prevents unintended power-off or settings changes when the sight contacts holsters, gear, or during handling. These features ensure consistent performance without disruption from inadvertent button presses.Automatic Brightness ResetAutomatic brightness reset instantly adapts the dot intensity to changing light conditions when powering on, eliminating manual adjustment delays when transitioning between environments.The Burris FastFire E delivers enclosed emitter reliability, exceptional battery life, and professional-grade performance-trusted protection for any mission.SPECIFICATIONSManufacturer: BurrisModel: FastFire ESight Type: Enclosed Emitter Red DotDot Size: 3.5 MOADot Color: GreenMagnification: 1x (parallax-free)Window Size: 22mm x 17mmConstruction: Monolithic machined 7075 aluminumEnvironmental Protection: Waterproof, shockproof, fogproofEmitter Protection: Fully enclosed (mud, snow, debris resistant)Brightness Settings: 8 total (6 daylight + 2 night vision compatible)Battery Type: CR2032 lithiumBattery Life: 60,000 hoursBattery Compartment: Side-mounted (no zero loss replacement)Always On Feature: YesWindage & Elevation Adjustment: 100 MOA total rangeAdjustment Type: Tool-freeLens Type: Aspherical (distortion-free, glare-resistant)Mounting Footprint: Aimpoint ACRO compatibleMounting System: Secure clamp with T10 tool (included)Features: Brightness lock, button lockout, automatic brightness resetApplications: Pistols, shotguns, carbinesIncluded Items: FastFire E Optic, T10 Mounting Tool, CR2032 Battery
