If you're looking for a small optic that offers big performance, look no further than the Holosun 507K X2!
Designed with subcompact and slimline models like the 43, 43X, and 48 in mind, the 507K X2 is perfectly sized for concealed carry!
Featuring a Circle Dot 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!
