All this talk about barrel pins has got me wadering about correct length. My Yugo pin is .125" short of reaching the outside edges of the trunnion (.0625 on each side). It is the same pin that came out of the kit.
The pin on my Bulgy kit that I had to drill out is slightly longer than the trunnion width. This seems more correct.
I also noticed that the pins that CNC Warrior sell are slightly long compared to my trunnion measurements. About a tenth inch longer.
Should I look into replacing the pin on my Yugo?
