Iam using the 1902 rear sight. I had a spare rear sight so I tried to modify the peep but it didn’t pan out so Iam shooting the “notch”.

I shoot the 1902 with the Sgt Peep.  I modified mine per CMP rules.  The original peep aperture is painfully small at approximately 0.04 dia.  I also modified a spare sight using wire gauge drills to 0.07 dia., which helped.  However, that was about as large as I could go before damaging the area of the peep.  Still, I wanted to get a little bigger so it would be easier to get back on target during the rapid fire phase.  So I built up the plate with JB Weld, and then opened the peep up to 0.1 diameter.  That really made a difference!!!
