Thats all the response you deserve...
“Hitting the mark with iron sites (no scope) at 300 yards.”
I won’t dual with you.... 300 yards is very good.
I have a Rock River LAR-15, 5.56 with EOTech optics and I would never bother to try to reach that far out, because I know I’d miss the mark. LOL
Anyway, you might not be a bad guy in person, but you need to deal with your PDS.
Good luck.
