You are better off with a larger aperature for the rear, so use the standard rear sight. This will produce a better "ghost ring" with the front.
I used a standard rear sight ..............1911_Mitch said:I am having Smith Enterprises build up a LRB/TRW rifle. I just about have all my parts together.
I want to use the Smith gas lock HK style sight, but am not sure about the rear sight.
Should I use a NM rear or a standard. What aperture size (.052 or .059) if NM ? What is the aperture size of a standard?
