Well, I almost bought an AR, but went with this. I do not regret it at all. Quieter. More ergonomic. Easier to clean and take apart. This is my 1st rifle. I never held one that I cared for. And, I am right handed but left eye dominate. The high eotech is great for me using my left eye.
Since buying it, however, it has ignited my interests in rifles. I've also found that while I love using my left eye for close distances. My right eye actually sees better at a further distance. So, at 50 yards and beyond, I'm still using the right eye. So, because of that, I kinda want an AR now. Still haven't decided if I will, because I'll have to sell 1, or 2 pistols, depending on which AR I would get.
But, the PS90 is my dream rifle. I have it set up like I want. And, while the short barrel does look kewl, I pick up more velocity with the longer barrel. And, after what I read tonight, I'm not really worried about the ammo wounding potential (I might have been if I had a 5-7 pistol).
If I can get my hands on more 195, I may switch over to that, and make the minor sight in adjustments I might need to (I've used 197 exclusively so far). The 195 is sufficient for what I want the gun for. I have no plans to shoot past 100 yards, and 90% of my shots are at 50 yards because 100 is just to damn far to see w/o magnification.
