Where did you get that 20mm rail, and how did you attach it?
But yea, ugly it up a bit.
And as someone who has had to wear tactical gear, for the most realistic 'weathering', try to think of spots on the helmet that might catch on something, 'grabbing edges', or just repeatedly rub on something, like my (Kevlar) helmet cover was worn on the very top because of how I threw it around when I took it off. Branches, bulkheads...seatbelts. One time I got stuck on a doorknob while clearing a room during a training op, by my camelbak. That was kinda embarrassing.
