i will possibly change that soon

I'm pretty sure that ammunition is not supposed to be changed except for golden and event skins. Look at the M249 and RPG on this page; The warhead and the belt aren't changed.

you can change it if you want, since it dont will change the skin so much

1.) I found 2 exceptions to this "rule" which are the pink and duck hunt skins on minigun but I still think you should keep the old ammunition since every other non event/golden skin does it too.

2.) I might be wrong but I think this is rule from PR and even if it isn't I don't think it would be good choice because it messes with the game's semi-realistic art style.

i never saw pr talking about that rule. and the semi realistic style doesnt matter much for a skin
also i guess the only thing you cant add to a gun is 3d details and stuff like that. except if its a exclusive or event

few parts like the iron sight, stock, and tip of the barrel should be colored black. visible ammo should revert back to their original texture, other than that i like it

barrel and iron sights should be black as stated above. they look kind of as if the barrel and body of the m249 are just one large plastic mold

cool nonetheless

I will soon remake the skin, ill try to make it look as you mentioned, thanks for the advice.

I barely know the basics of blender plus this gun is a freemodel i took from roblox library, so if i were to paint other parts, i would have to make a completely new texture for the gun. With this one its impossible.
