Ever notice how the aperture sight fan club is mostly old guys? I can sure relate to that, having hit 73 last month. Had my Lee-Enfield #4 Mk 1 in the deer rifle rotation last fall. Nice rear aperture with a flat top front sight. Woods I hunt won't even give you a glimpse of a deer past 100 yds. Had it out a couple times but no shots were offered. Front sights on M-1's and M-1A's used to get some of that "sight black" when I shot NRA High Power back in the 1990's early 2000's. The rear apertures on them are great, IMHO. Haven't seen sight black in years, it was wonderful for that reflection and glare stuff.
