AR-15S are not military grade weapons they are civilian versions of military grade weapons called M-4A1s i know it's hard for you left minded folk but try to get you facts straight. However thank you for finally showing how truly ignorant you are. First you try rebut by argument with a outrageous comparison with rocket launchers and nuclear bombs then completely ingore that part and now you go straight after a very specific weapon that the media has chosen to completely warp. An AR-15 in the hands of a wrong person is just as dangerous .22 cal pistol. By the way there's 2 key words that sentence but I doubt you will see it with how narrow sighted you are in regards to guns. You're right you can buy a gun at a gun show with out a backround check IF it's through a private sell. Not everyone at gun shows are private dealers only about 5% to 10% are the rest are authorized gun dealers and they do background checks oneveryone. During a private sell however the person buying and the person selling have to be a resident of that state that's not a big rule but it limits of someone from a state with (stricter gun laws in terms of buying guns) from buying a gun. The person buying the gun has to show a Concealed weapons permit that proves to the seller that he's already gone through a backround check and doesn't need another. It's not a perfect system and could be improved but as a proud gun owner and an avid seller this procedure happens everytime. Anyway I'm fairly certain your political standings are somewhere out in left field and I know no amount of facts and evidence no matter how much is literally spoon fed down your throat you will still disagree and form yet another stupid and completely outrageous analogy comparison to how (guns) are the issue so I hope you enjoyed the read but I'm muting you have a great day with that limited Brain of yours.
