Is that a M16A1? In 2003?
it does not look to have a brass defector on the side. Whatever it is, SMS needs to clean it.
Original Colt USAF 604 profile M-16. Our armory was actually converted to A2s while we were deployed. Turned those in when we got home and they got converted as well.
The parts that needed to be clean were clean lol. Didn’t care about keeping the ever present dust and dirt off the outside...I hadn’t had a proper shower in about a month at that point lol.
