The 407K: Simpler reticle than the 507K, and more affordable.
That's all, folks: The Holosun 407K -- the sibling to the popular 507K pistol red dot -- is now available. It features the same rugged, squared up aluminum housing, durable multi-coated glass, and incredible battery life. The only difference is the 407K's simpler 6-MOA red dot reticle, which ditches the 507K's more complex circle-and-halo dot.
The 407K features the same RMR cut, too. This ensures it's compatible with plenty of optics-ready GLOCK, Polymer80, and other custom slides.
