Holosun HE507K-GR X2

In addition to the standard red version, the Holosun 507K X2 is now being offered with a green reticle— HE507K-GR X2 —providing a high-contrast aiming point that is equally suited for rapid target acquisition in both daytime and low-light conditions. Holosun continues with desirable features, such as Shake Awake, Multiple Reticle System, Super LED and more are standard here.

Measuring just 1.6"x0.98"x0.95" and weighing only 1 oz., optimized for concealed-carry applications, the compact HE507K-GR X2 boasts an impressive 50,000-hour run time off of one CR1632 battery (on Setting 6), and a side-mounted compartment allows the unit’s battery to be replaced without the need to remove the optic from the gun, which could potentially affect its zero. The water-resistant, reflex-style optic has 12 brightness settings, two of which are night-vision-compatible.

Holosun’s Shake Awake, activated by an on-board motion sensor, instantly powers the unit’s LED, deactivating the programmable Sleep Mode feature in fractions of a second—simply raise the unit, and it is ready for use. A Multi-Reticle System gives users a choice between three reticle options: a 2-m.o.a. dot enclosed within a 32-m.o.a. circle, only the dot or only the circle.

Retail price for the HE507K-GR X2 is set for $376. To learn more, please visit holosun.com.
