On a side note: you mentioned the Eotech on the F2000 was slowing you down. I'd love to hear more on that as I have finally decided on one of those with a magnifier over an ACOG. Due to what I feel was better clarity, reticule and ease of target acquisition. If that is too far off topic, I'd love to hear from you offline.
This would apply to one mounted on a PS90 Tri Rail too, so we'll delve in to it a little. Keep in mind I'm not trying to bash EOTech - I like them.. just not head over heels about them anymore like I was when I first got one almost a decade ago.
The problem I have with EOTech isn't necessarily speed, they're damn fast. The problem I have is the grainy reticle - it makes it REAL hard to put precise shots on target at any sort of distance. This is exacerbated if you change brightness levels. (or light conditions change, changing the 'relevant' brightness)
Try this exercise sometime if you have an EOTech and a 100+ yard range: Turn the EOTech down as far as you can still see it, and shoot a 10 shot group from the bench. Then turn it up as far as it'll go, and shoot a 10 shot group from the bench. The 'haze' that it starts to create makes it very difficult to keep a consistent point of aim.
The problem I have with shooting it long range is A) lighting conditions outside change constantly even in the same range session (especially if it's partly cloudy), and B) I rarely set it to the same brightness level with any sort of consistency.
The "wash", or "blur", or "haze", or whatever you want to call it, from the EOTech reticle, makes it very difficult to be precise. It's great for it's intended use - putting shots on target fast at close range. But when you need to reach out beyond 100-200 yards, it becomes a serious handicap.
To be fair I haven't shot one with a magnifier tube; but at the price point those EOTech combo deals are sitting at you're in ACOG and Nightforce "true" 1x-4x territory. (Leupold also has one I was looking at as well.)
The thing I've proven with this little PS90, is even with a 1x non-magnified optic, I'm able to hit very consistently at 200 yards (2 MOA or so), and even get the majority of shots on target at 300 yards. I simply *can not* do that with an EOTech. (If I take the EOTech off and shoot irons on the FS2000 I get about 1.5MOA groups from the bench, so I definitely know it's not the rifle...)
Anyway, that's my take on it. My needs go beyond a simple "reflex" sight which red-dots and Eotechs give. I need something that can serve as a decent reflex sight AND let me reach out to 300+ in a pinch.
The only way to do that with any consistency is to have a non-projected reticle. A projected one just doesn't cut it for precision work. (Particularly the grainy Eotech ones..)
