Re: FN PS90 USG vs Tri-rail
I had a PS90 with the white donut and had no problem with it but almost all my buddies did, sold it and bought another with the SS sight and black donut in aluminum housing instead of plastic for the white one, now everybody likes the sights.
Shoting it with both eyes open is a breeze and hit on clay bird sitting on berm at 150 yds are easy. I have tried the try rail model with AEotech and they are too high for me and too wide. the SS sight is perfect, day and night, compact and light weight.
hope this helps.
