I think the reason some sights have ranges marked on the bottom as well as the top is so that you can adjust the range while staying prone, that way you don't have to move the gun around or stick your head up to change settings. I think early Kar.98ks were marked like that too.
Falloutlover5443 nailed it, the settings on the bottom of the sight leaf were intentionally put there. That way you can keep your firing position without having to move and potentially expose your head/body to adjust the sight. Russian RPK’s and RPK-74’s are like this as well.
From what I understand, Serbian paramilitaries painted their wood black as an identifying mark. I bought a set from Apex and it’s on my AB2 underfolder
@@AK-John_Official are the trunnions marks in any way? The early ones were always unmarked, zastava logos only found their way starting on early 80s examples of if I recall. Great work as always!
