Holosun Technologies has been adding to their product line with some very impressive offerings. I’ll be reviewing one of their newest open red dot sights, the HE407K-GR X2. This is a green 6 MOA dot designed around the compact pistol frames, but as you’ll read in my upcoming review it is quite at home on a large frame tactical pistol. It does so with grace and a very clean lower profile. The 407K-GR X2 gives nothing up to a larger pricier sight, and it is waterproof to boot. Catch my upcoming review this September.
