Bikkuri, the muzzle is Blue.
Blue guns are training guns. Like the ones used for Simunition training.
JAG officers, even in a combat theater, would normally only get an M9. And if an admin type did get a rifle, given the uniform he’s wearing, they probably would have gotten an M16. I’m sure you know the difference.
Yup.. It was a pic pose only. Means nothing..
