So I've been working on this character, a Monster-Hunting Texas Ranger, who is a Gunslinger and Gunsmith so he can modify and improve his own weapons. Would this allow him to add aspects to a given gun? I'm thinking of simple stuff like "Laser Sights", "Reliable", "Polymer Construction", "Scoped" etc...
Come to think of it, I can even see it added to non-gun weapons, "Razor-Sharp Edge", "Whistling Bulb Arrow", "Extra-heavy Head" or "Poisoned" though for the sake of this post I'll stick to Guns.
I would think these would be considered "Sticky" aspects that could be tagged the same way as other Aspects; with fate points or maneuvers and such.
For RP sake and flavor sake and not wanting to unduly break the game I'd like to work out a reasonable way to make such mods work so any help is welcomed. What kind of limits should be placed on modifications? I already figure that it has to be a mod available for the weapon currently (i.e. no death rays) and should fit the weapon its being attached to and the Aspect should be appropriate to the item.
