Hello. Im new to the forum. Hope you don't mind me making a post that might have already been on here. I'm going to be moving to MD shortly from PA. Needless to say im in for some big changes when it comes to my 2nd amendment rights. But that's another topic. So i own an AR that is chambered 45 acp. It is a bazooka Bros lower and 45 olympic upper with 16'' barrel. I bought this a number of years ago and its a fun little rifle to shoot. I contacted a local msp barrack and they couldn't tell me for sure if this set up is ok in MD or not. I called Annapolis 2 times and left messages for people to call me back and they never did. I the called a few gun shops in the area i am going to be living and they seemed to think it would be ok. As much as i don't agree with the law i am a law abiding citizen and id like to know for sure if i can own this or not. I like going to the range and wouldn't feel comfortable taking this with me with all the unclarity. Thanks for any insight you may have.
