HOLOSUN HE407C-GR X2 2 MOA Dot Open Reflex Sight - Compact Pistol

In this review of the HOLOSUN HE407C-GR X2 the bottom line is simple: this open reflex sight is aimed at shooters who want a crisp, low-profile 2 MOA aiming point for full-sized handguns and reliable battery life management. The reviewer found the combination of a bright green 2 MOA dot, a wide 0.63 x 0.91 in window and a rugged 7075 T6 aluminum body makes the sight well suited to duty, competition, or serious range use where quick target acquisition and durability matter.

Key Features

• Green 2 MOA Dot: The precision 2 MOA reticle gives a small, clear aiming point that helps improve accuracy at typical pistol distances.
• Long Battery Life: Holosun's Green Super LED and efficient electronics offer up to 50,000 hours of battery life for extended use between changes.
• Solar Failsafe: Built-in solar backup keeps the reticle visible if the CR1632 battery fails and ambient light is available.
• Shake Awake Technology: The optic conserves power by deactivating the LED when idle and instantly reactivates with the slightest movement.
• Durable Construction: The 7075 T6 aluminum housing and anodized finish provide a rugged package for harsh environments and regular carry.
• Easy Battery Access: A side-mounted CR1632 tray allows quick replacement without removing the sight from many mounts.

Who It's For

The HE407C-GR X2 is for handgun owners who need a compact, parallax-free red/green reflex sight with unlimited eye relief and a small 2 MOA dot for precise aiming. It suits competitive shooters, duty shooters, and recreational users who value straightforward controls like Lock Mode and automatic brightness adjustment.

Shooters who prefer larger reticles for extremely close-quarters speed or those who insist on magnified optics should look elsewhere; this is a 1x non-magnified reflex sight designed for full-sized pistols rather than a magnified or tubular scope.

Pros & Cons

Pros

• Crisp, easy-to-see green dot that performs well in daylight and adjusts automatically in varied lighting.
• Excellent battery management with Shake Awake plus Solar Failsafe for redundancy.
• Sturdy 7075 T6 aluminum housing and industry standard footprint for wide mount compatibility.
• Simple maintenance with side-mounted battery tray and Lock Mode to prevent accidental changes.

Cons

• The small 2 MOA dot favors precision over super-fast target acquisition at very close range, which some shooters may find limiting.
