Hi everyone, Im running a char that i was planning on taking the grunt perk with. Now on the wiki i know it says that the gra ac is not affected by grunt. What i was curious about is whether or not you can apply the GRA mods to the standard assault carbine?

Don't believe you can. Only the standard increased magazine size mod can be added to the regular gun. It won't have GRA in the name when you buy it. Kinda crappy that you can't add the gra mods to the regular gun.
