Would be a wise idea to add one to your “wip” list. Cuz, it makes no sense that practically all of our ranged weapons have no access to scopes/sights/extended mags/high-capacity batteries/larger tanks and the like. Especially considering all of these weapons have access to these things within the 40k universe itself.
It makes things like the Helbore, the Boltgun and several other weapons far more difficult to use than is necessary.
