Norm is correct. KY does NOT have a mag limit, only the Federal laws apply. Unless you are a LEO (for official use) or they are issued by the military to you, for official use (and you are active) you can not possess any hi cap POST ban mags. Buy and possess all the pre ban mags you want, and enjoy your AR. Oh, so long as there is no local ordnances in your city that say other wise, but I doubt it. Email me directly, tell me what city your in. Look in the FAQ at this site for GREAT explanations and more info.

Edited to add: Norm, and all you pro gun, law abiding, willing to work people in NJ and NY, pack your stuff and move down here. I was born in NY, raised in NJ, came to KY and fell in love with firearms!!!!!!!!
