Mini;

It's not very common and I personally do not recall seeing any images of second uppers strapped to packs. However I am certain that second upper receivers are issued as required to specific individuals (Typically the marksmen who double as assaulters). Is it likely that they would run on the field with the second upper? Not very likely. Would they have a second upper on-base? Absolutely.

Dirt is something that will be picked up over time, same with the wear on my weapon. I'll be sure to post more pictures in the next few months when things have had a chance to get really filthy
