.rez weapon mods

ok i have a question when you modify a weapon like the m16 to m417 combat will it be as deadly and have the same recoil as the m417 combat jw cause i never knew if it was just for looks or if it was really that BA

If you're smart to read all the other ones who posted the same thing as you, you would know. You need to crack Attribute.rez to do it.
