My Mosin's sight pin is too large.
Occasionally we have customers reach out and tell us that that have had issues with their sight pins being slightly larger. Most of our customers have no problems, but for the few that do find that drilling the hole where the sight pin goes (slightly larger) works well.
Simply choose a drill bit the same size as your sight pin, and drill the hole in the mount using a drill press. If you’re careful a hand drill also works well but we recommend clamping the mount down to your workbench.
If you scratch the surface of the mount most have good results with a black sharpie for filling scratches. If you have other questions please contact us.
