BI 7-4 Front Sight ... Held In-Postion By Screw

Here are a few pictures of the front sight on the BI 7-4 used by Kevin6q.

I always thought this was an oil hole for lubing the spring.

Just maybe it was the access hole for some kind of set screw that keeps the sights in place.

Taking off the snow cover required grinding off the end of the pin which acts as a hinge
and also runs through the plunger inside the spring.

A 4d nail pushed it right out and looking down into the hole I saw a slot.

Inserting a screwdriver and giving it a twist had the sight held firmly into place.

If anyone was wondering how to remove the front sight its held in place
by a single set screw hidden by the spring.
