Well just shipped my first rifle to California. I sold a Kel-Tec Sub 2000 Glock mag 9mm to a nice guy in Bakersfield Ca.He sent all the necessary compliant stuff such as bullet button (wich is the stupidist thing ive ever done to a rifle before) and a stock extension. The buyer drop shipped these to me so i put them on with no problems. I am not an FFL dealer just an individual Thru gunbrooker. Gun had 10 rounds thru it and i just didnt like it. Well payment was recived and it went to his FFL of choosing. All recipts manuals extra parts sent in orginal Kel-Tec Box thru usps Insured with tracking number. Made it fine gun intact no problems at all with the Us Mail. well the dealer opens it and complains that I donot have the correct paper work ie..california shipping authorization number and My FFL paper. Well im an individual and do not need a single one of those i explain. Then he askes how did you perform those california complaint upgrades and able to ship a new gun (gun was used)with out being a dealer. I said how long have you been a dealer for he says Late 09 i said maybe you need to read your own gun laws. Long story short he let the buyer pick it up......
