Holosun HE407COMP-GR6 Green Dot Competition Reflex Sight, 6 MOA

Holosun HE407COMP-GR6 Green Dot Competition Reflex Sight, 6 MOA

The Holosun HE407COMP-GR6 brings a bold 6 MOA green dot to the 407COMP lineup, delivering exceptionally fast visual pickup and enhanced brightness in a wide range of lighting conditions. Green reticles are often perceived as brighter to the human eye, which can make them easier to track during rapid strings of fire or under harsh outdoor lighting.

Designed for competition shooters who demand speed and clarity, this optic features a generous 1.1 x 0.87 inch viewing window that supports fast transitions and improved target tracking. The housing is precision machined from hard-anodized 7075-T6 aluminum for strength without unnecessary weight. A convenient side-loading CR1632 battery tray allows for quick battery changes without removing the optic or disturbing your zero.

Holosun’s Shake Awake technology extends battery life by powering down the LED when motionless and instantly reactivating with movement. With Memory Mode, the optic returns to your last brightness setting when powered back on. Rated IP67 waterproof and vibration resistant up to 5000G, the HE407COMP-GR6 is engineered for reliability in demanding environments including USPSA, IDPA, Steel Challenge, and intensive range sessions.

Frequently Asked Questions (FAQ)

What footprint does the Holosun HE407COMP use?
The Holosun 407COMP uses the industry-standard Trijicon RMR mounting footprint. This ensures compatibility with a wide variety of aftermarket slides, mounting plates, and adapter systems.

Why choose a 6 MOA green dot for competition?
Many shooters find that green reticles appear brighter and more defined to the human eye, especially in bright daylight. A 6 MOA dot is large enough for extremely fast acquisition, making it ideal for USPSA, IDPA, and Steel Challenge where speed matters.

What battery does the Holosun 407COMP use?
It operates on a single CR1632 battery. The side-loading battery tray allows you to replace the battery without removing the optic or re-zeroing your pistol.

Does the Holosun 407COMP have Shake Awake technology?
Yes. The optic automatically powers down during inactivity to conserve battery life and instantly reactivates to your last brightness setting when motion is detected, which is valuable for both competition and defensive setups.

Is this reflex sight good for USPSA or IDPA?
Absolutely. The oversized competition window and fast-acquiring 6 MOA green dot make it a strong choice for USPSA, IDPA, Steel Challenge, and high-round-count training sessions.
