[Hectic]

So ive searched around and cant find an answer so im asking.
I know the pro sniper version doesnt have the rail/scope mount on it but im wonderisng if it has the holes pre drilled for installing the mount or would i have to drill and tap em myself?
Anyone who knows can please fill me in, im kind of in a spot now was going to get a gspec but now they dont have any and only have pro sniper may be a month or more befor they get gspecs in so i was gonna just get the pro sniper version if i could easaly install the rail.
