Hey guys, I have a FSB I was wondering if anyone could help me identify.

It has an "F" stamped on one side and "3DI 1" on the other.

Also, anyone else on here have a NOVESKE N4 lower with the KNS anti-rotational pins installed?  I seem to have a small gap between the outer receiver and the KNS cover plate.  I know the instructions say "snug" the screws, I actually went a little past snug to try to eliminate the gap, but no luck.  It seems almost as if the hammer pin is a little too long.

I don't have an N4, but I do have a Noveske lower that had KNS pins for a while. The gap is not unusual with the KNS pins installed on many lowers and does not affect function.
