Subject: [Milsurplus] ART-13 knobs question
I had never noticed the difference in color of the knobs on the ART-13.
Kinda reminds me of this puzzle in the local newspaper – “Find 6 differences in the drawings”
and the tendency is to overlook what’s “not important”.
So why the red knob skirts and some black ?
