1903 Reduced Aperture


Temporarily Out of Stock

SKU: N/A Categories: ,


USGI sight apertures for the 1903 with a reduced aperture soldered in.  Fully legal in the CMP ‘as issued’ class.


The amount of blur your eye sees is directly proportional to the aperture diameter, so dropping from a USGI .070 to a .042 aperture produces only 60% as much blur (ie a 40% reduction).


Apertures are available in 0.042, 0.044, 0.0465, 0.052, or 0.0595.
