Press Release


City of Industry, Ca. –Holosun is releasing several new models with their Super Green LED including the 507K series. Green reticles have some advantages of being an ultra-high contrast color in both daytime and low-light use. The brilliant green reticle of the HE507K-GR X2 enables the shooter to obtain a sight picture instantly against almost any backdrop or lighting conditions.

HE507K-GR X2 is an open reflex pistol optic designed primarily for concealed applications. The HE507K has become the go-to optic for concealed carriers and professional users on backup firearms. The HE507K features HOLOSUN’s Multi-reticle System (MRS) which gives the user an option to use the 32MOA/2MOA Circle-Dot reticle, Circle only, or Dot only. With up to 50,000-hour battery life (on setting 6), is the 507K goes far beyond the industry standard for a green reticle. It also has 12 brightness settings – 10 daytime and 2-night vision-compatible – for all-around use capabilities.

When carrying this optic, there is a wide range of features worth noting. Lock Mode is one such feature. It locks out the button functionality, preventing accidental setting changes if the optic is knocked into something. This, paired with the button redesign adds to the streamlined design which is perfect for concealed carry and backup firearm applications.

The HE507K is very compact measuring just 0.95” tall, 1.60” long, and 0.98” wide. Additional features include a side-mounted battery which enables the user to replace batteries without removing the optic which can require re-zeroing every time.

Overall, this newest addition to the Holosun lineup is worth a closer look and a few glances downrange.
