The other day I visited a pawn shop in Elizabethtown Kentucky. When I was in there I was looking over some of their firearms, which were over priced. I noticed a gsg-5 2lr (mp-5 clone) and noticed something very wrong. This particular firearm had a short barrel with a short birdcage flash hider that was not permanently attached to the barrel. Upon closer inspection I came to the conclusion that this "rifle" had started life as a pistol and someone then put a stock on it making it a short barreled rifle. There was no one to be found in the store who worked there in the few minutes I was in there and had to leave. Once I got home I called the pawn shop and told them I believed that firearm to be a SBR, and then told them it was an illegal firearm as I understood the law. I told the gentleman he may want to I quire about the law because it could cost him his business if my understanding of the law was correct. This "gentleman" then proceeded to cuss me out and tell me that he would sell it as a pistol with a rifle stock, which I told him I didn't believe was legal. After a few more minutes of cussing me he hung the phone up. Was I wrong in calling him and telling him it might be worth looking into and informing him on my interpretation of the law? Be definitely was not pleased with my phone call at all.
