Curio status of Artillery Stock

[Ron Wood]

Ed is correct that a reproduction stock is legal so long as it closely approximates the original item in size and configuration. The usual restriction applies that you can't mix types; e.g. an arty needs an arty stock, a navy needs a navy stock, etc. I would add to Ed's comment about a 4 inch Luger. You may own a stock and a 4 inch Luger only if you also have another appropriate Luger to go with the stock. It is a fine point, but if you only own the stock and the 4 inch Luger, that constitutes the "intent" to construct a short barrel rifle even if you never attach it.
