This Holosun 507K is a collaboration between Holosun and Primary Arms. The patented ACSS Vulcan Dot Reticle has a larger circle around the dot to aid in sight acquisition. Designed with subcompact and slimline models like the 43, 43X, and 48 in mind, the 507K X2 ACSS Vulcan is perfectly sized for concealed carry! This optic uses the same K footprint as the original 507K.
Featuring a ACSS Vulcan reticle with 12 brightness settings, and up to 50,000 hours of battery life, and Holosun's Shake Awake technology, the 507K is always ready when you are.
The X2 also adds the Lock Mode feature, which prevents accidental changes to the settings by locking the adjustment buttons. The buttons themselves have been redesigned to be lower and out of the way, but still easily accessible!
