posted on June 21, 2023

Holosun has just started shipping the new 507Comp slide mounted electronic red dot optic. This new “big window” sight is parallax free and unlimited eye relief competition oriented electronic red dot sight is probably one of the most anticipated products released in the optics category for 2023. 

The most distinctive feature of the new Holosun 507Comp sight is probably its “big window” objective lens. It measures 1.1 inches by 0.87 inch and is designed to grant the shooter a wide field of view in order to make shooting targets and target transitions more effortless. The other feature is the 507Comp is Holosun’s CRS (Competition Reticle System), which consists of a 2-MOA dot, an 8-MOA ring, a 20-MOA ring and a 32-MOA ring. By holding down the “-” button for 3 seconds, the shooter can cycle through multi-reticle options such as different combinations of the 2-MOA central aiming point and the larger 8-, 20- and 32-MOA rings. Additionally shooters can also shoot with the smaller dot itself or with the larger rings and no central dot. All of these choices give shooters a wide latitude to best match their reticle size to the specific targets found in their competition style.  

The 507Comp has a battery life of 50,000 hours and has six daylight and two night-vision-compatible settings. Although its primary focus is competition, Holosun also designed the 507Comp around durability. The sight has a 7075 T6 single piece aluminum housing to protect it from shock, bumps and drops. Like all other Holosun optics, the 507Comp has click values of 1-MOA-per-click and includes a combination T10 Torx and mini flathead tool in the packaging. MSRP for the 507 Comp varies from $435 to $470, and for more information of this optic or other products from Holosun, please visit
