This is an edit of what I believe the sight would appear like. While I couldn't find images of the real K-14's sight specifically, I have used a number of other gunsights from the WWII era to get the best effect I can out of this.
The fixed sight has a more of a glowing appearance, and an increase of red, particularly in the bottom section of the sight. I have not touched the gyro sight, because the diamonds are cut sideways out of a straight line. I can not add a convincing glow effect to them without it looking very wrong, so I let it be. This mod only affects the fixed sight.
This mod passes the Integrity Check.
