I'm sure it has been asked before,but can someone help me understand the laws concerning carbine kits? Several years back I picked up a carbine stock set in a trade,but I only have pistol barrels.I haven't used the stock on my receiver,because I have no barrel in carbine or rifle length.I was reading,and trying to understand the BATF regs concerning this situation. It seems to me,and I'm no lawyer,that merely posessing the shoulder stock without assembling a short barreled rifle could put me in violation.The wording "in close proximity" was used,so I am thinking it isn't a very good idea to keep the carbine stock in my safe with my pistol length barrels.Maybe I shouldn't keep the stock in the house at all.I suppose the easiest solution would to be to buy a carbine barrel. I suppose I could register the receiver as a short barrel rifle but wouldn't that make it illegal to use my pistol barrels on it? Any chance I might get some free legal advice here?
