1). How do you like them?
Love it!
2). How does it load/perform for you?
Loads long ~_~ it's 2MB per file... when I open all of this in tabs my browser freezes for some reason o_O
3). Should they be smaller/bigger/removed?
Let them be

Though in general - 300px wide images would work better I think. Both performance-wise and they would fit all the other infobox images.
Idea: Maybe try to put only a cut from middle - like... smaller FOV. To show more of actual fire effect than all the surroundings.
4). Would you like to see more animated gifs for other weapons pages?
Sure!
