Look no further than the ELCAN SpecterOS 3.0 Combat Optical Sight. Engineered and manufactured to the most demanding standards, this 3x optical sight is a robust, lightweight, and highly versatile solution designed to give you a definitive advantage in the field. When your mission demands rapid target acquisition and unwavering accuracy across diverse scenarios, the SpecterOS 3.0 stands as a premier choice, bridging the gap between speed and surgical precision.

What Problems Does the ELCAN SpecterOS 3.0 Solve for You?

Modern combat and security operations require gear that can adapt instantly. Traditional optics often force a compromise: either you choose an optic optimized for CQB, sacrificing long-range accuracy, or a precision scope that’s too slow for dynamic, close-in threats. The ELCAN SpecterOS 3.0 eliminates this dilemma.

• Problem: The need for rapid engagement in close quarters and precise aiming at distant targets from a single optic.
  Solution: The SpecterOS 3.0's proprietary Rapid Aiming Feature (RAF) allows for lightning-fast target acquisition in CQB scenarios, while its precise 3x magnification and ballistically-calibrated reticle ensure pinpoint accuracy for targets up to 600 meters. This unique dual capability means you don't need to switch optics or rely on secondary sighting systems.
• Problem: The risk of optic failure due to harsh environmental conditions or accidental impacts.
  Solution: Constructed with a one-piece aluminum housing and reinforced with shock-absorbing rubber bumpers, the SpecterOS 3.0 is built to withstand the most severe stresses of modern combat operations. It is rigorously tested to be shockproof up to 450 g's and waterproof to a depth of 66 feet for a minimum of two hours, ensuring reliability when it matters most.
• Problem: Difficulty maintaining zero after mounting/dismounting or during intense use.
  Solution: Featuring a single wing nut attachment system, the SpecterOS 3.0 offers exceptional return-to-zero repeatability. This means you can confidently remove and remount your optic without significant loss of zero, a critical feature for professionals who depend on consistent performance.
• Problem: Poor visibility of the reticle in varying light conditions, including low light or night vision compatibility.
  Solution: Its battery-powered LED illumination system offers 11 visible brightness settings for daylight and twilight conditions, alongside 3 dedicated settings for night vision devices, ensuring optimal reticle visibility across the entire spectrum of operational lighting.

Deep Dive into Core Capabilities: The ELCAN Advantage

The ELCAN SpecterOS 3.0 isn't just another optical sight; it's a meticulously engineered tool designed for peak performance.

Rapid Aiming Feature (RAF) and Versatile Reticle

At the heart of the SpecterOS 3.0's versatility is its innovative Rapid Aiming Feature (RAF) paired with a sophisticated dual-thickness crosshair reticle and integrated range finder. This design allows for incredibly fast target acquisition without sacrificing precision.

For close-range engagements, the wider, thicker portions of the crosshair guide the eye quickly to the target, enabling instinctive aiming and rapid shots. This is particularly beneficial in dynamic CQB environments where fractions of a second can make all the difference. When the situation transitions to mid or long-range, the finer, central portion of the crosshair, combined with the 3.1x magnification, provides the precision necessary for accurate shot placement.

The integrated range finder further enhances the operator's capabilities, allowing for quick and accurate distance estimation to targets. This is especially crucial when engaging at varying distances without the time to utilize separate rangefinding equipment. The reticle can be supplied with a ballistically-calibrated pattern specifically for 5.56mm ammunition, optimized for ranges between 100 meters and 600 meters, ensuring that holdovers are intuitive and precise. Alternatively, models with calibrated external elevation and windage adjustments offer the flexibility to dial in precise corrections for various ammunition types or specific engagement scenarios.

Unwavering Durability and Construction

When operating in austere environments, your equipment must be as resilient as you are. The ELCAN SpecterOS 3.0 is a testament to rugged engineering. Its one-piece aluminum housing provides a foundational strength that resists bending, twisting, and impact, maintaining optical alignment even under extreme duress. The exterior is finished with a durable black anodized coating, providing excellent resistance to corrosion, scratches, and wear.

Further enhancing its resilience are the strategically placed shock-absorbing rubber bumpers. These aren't merely cosmetic; they act as a protective exoskeleton, dissipating kinetic energy from drops and impacts, safeguarding the delicate internal optical components. This level of physical integrity is why the SpecterOS 3.0 is trusted by elite military and security units worldwide. It's designed to survive and perform through accidental drops, vehicle vibrations, and the concussive forces of weapon recoil, making it an indispensable asset in the field.

Superior Optical Performance

The SpecterOS 3.0 delivers exceptional optical clarity and a wide field of view, critical for situational awareness and target identification. With a nominal magnification of 3.1x, it strikes an optimal balance, providing enough magnification for precise target discrimination at distance without sacrificing the wide field of view (6 degrees) necessary for maintaining situational awareness in close-in engagements.

• Eye Relief: A generous 66mm eye relief allows for comfortable viewing and prevents "scope bite" during recoil, even when wearing protective eyewear.
• Exit Pupil: An 8mm exit pupil ensures a bright, clear image even in challenging low-light conditions, as it allows more light to reach the user's eye.
• Fixed Focus Range: The impressive fixed focus range from 20 meters to infinity means no constant fiddling with focus adjustments. Once mounted, the sight remains clear and sharp across all practical engagement distances, enabling immediate target acquisition.

Illumination and Power Management

The reticle's illumination is powered by a single CR123 (3V Lithium) battery, a commonly available and reliable power source. With an average battery life of 3.1 years, operators can depend on extended periods of use without frequent battery changes, a significant advantage during extended deployments. The 11 visible brightness settings allow the user to fine-tune the reticle intensity for optimal visibility against any background, from bright daylight to dusk. The addition of 3 night vision (NV) compatible settings ensures seamless integration with night vision devices, providing a tactical edge in low-light and no-light environments.

Precision Adjustments and Mounting Versatility

The ELCAN SpecterOS 3.0 offers precise adjustments to ensure zero retention and accuracy. With an adjustment resolution of 0.5 minute of angle (MOA) and an impressive total adjustment range of 120 MOA, operators can confidently zero their weapon system and make necessary corrections for windage and elevation.

Mounting the SpecterOS 3.0 is straightforward and versatile. It is designed to mount directly to MIL-STD-1913 Picatinny Rails, the industry standard for modern firearm platforms. Additionally, it can be securely attached to M16/AR15 carry handles, offering flexibility for a wide range of popular rifle systems. Optional MIL-STD-1913 auxiliary mounting rails are available, allowing for flexible attachment solutions for other tactical accessories like lasers, lights, or miniature red dot sights, further enhancing the weapon system's modularity.
