Testfire: Holosun HS403R

There are more than a few reasons why one might veer towards a red-dot as a sighting solution. For one, they’re fast to acquire over traditional iron sights, a statement that doesn’t really hit you until you try it on a timer. 

While it started with hunting, red-dots have become a staple of law enforcement and are a popular choice in certain military applications. The action target shooting community is also a big market for these sights, though in this arena the latest generation of low power variable optics (think Vortex Razor) which are a hybrid in some sense, are rapidly gaining traction.
