i just purchased a 17S this week. i took it out today to the range. the sights were not mechanically zeroed but i went ahead and shot anyways. at 25 yards set at 3 i didn't get a single hit. i then mechanically zeroed it and i got 3 hits. all very close. each touching eachother. shot very low and right. i made adjustments and did get elevation and windage on but in order to get centered i had to max out the windage. my barrel is off with the rail. should i keep it or send in to FN? im just concerned of what will happen once i put an optic on there. any help is appreciated. with all that being said i love how this thing shoots. its awesome.
