The following is some information provided by a friend from Culver's Shooting Page in response to inquiry made by me about the configuration of the front sight of the '03:

</font><blockquote><font size="1" face="Verdana,Tahoma,Arial,Helvetica,Geneva">quote:</font><hr /><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva">The front sight of an 03 consists of three pieces: fixed base, movable base, and the sight blade itself.
The fixed base is the part which is attached to the barrel, and is held in place by a spline which is an integral part of the barrel, and a cross pin, which goes through a hole in the base, and through the spline as well.
The movable base is held in the fixed base by a dovetail arrangement and a screw which enters from the front, which locks the movable base in place.
The sight blade is held in a slot in the movable base, and is locked in place by a transeverse pin.
The 03A3 is similar, except the base is one piece, and the spline is not integral with the barrel, but is a separate key fitting into grooves in the barrel and the sight base.

Please respond.
