I bought one of these rails to put on my LE PS90. When I drop it in there is extra space on the side. All holes line up, but I would have to tighten each side screw exactly the same in order to keep the rail straight. Is there a difference on the LE model that makes this not fit properly, and has anyone else come across this and found a solution? There is also an issue with the side rail on the LE version that must not be a problem with the standard model. By the way, if you need either rail Bullpup Armory has them (or did last week).
