I'm running it on my 18" Noveske at the monthly Pueblo tactical match. I'm looking at getting a second one. Problem is we can't keep them in stock. We have some right now, but a month or two and we will be out again. I bring my rifle in to work for people to see the Strike Eagle on a gun. The 1-4 Viper PST is better glass, but a more complicated reticle. The Strike Eagle is a fixed drop reticle set for a basic 16" barrel with 55/62gr ammo. It's less exact, but once you know your drops with your preferred ammo it's much faster to use.
You can swing by Bowers if you want to see one.
