Can Gun Runner's Arsenal Mods be attached to any weapon in Fallout New Vegas
I brought a couple of Mods for an Anti-Material Rifle and they have a (Gun Runners Arsenal) label in the Pipboy but i can attach the mods, i did pick up the gun in a location that was added via a Quest Mod that i installed but i'm wondering whether i need a weapon with the same (Gun Runners Arsenal) label on it to equip these mods or if it's because this Quest Mod added an Anti-Material Rifle which is different from the regular one

Even though Fallout Wikia states that some GRA mods can be used with non-GRA weapons, I cannot find any mod that actually fits the description. This means that all the GRA weapon mods require GRA weapons.
Edit: I just tested the GRA Assault Carbine Extended Mags mod on the normal version of Assault Carbine and it didn't even come up in the Mods screen.
1Actually not all do. There are mods for guns such as varmit rifles and laser rifles and hunting rifles that arent gra weapons. If the weapon has a copy that is (GRA) then you can only put it on the gra copy.
