Got off the phone with FN, I asked them about the models of PS90's they still make and found out a ear full.
PS90 USG (Black sight)
PS90 tri rail
PS90 standard (Rail with iron sight inside of the rail)
They told me that all models of the ps90 besides the "PS90 standard" was discontinued? Personally I think the PS90 standard rail look ugly and too big.
What do you think about this?
