this may have been discussed before but here goes. i have noticed that most people do not want a BOS and i am happy with that myself. i don't need one either but i have been told that a BOS protects you and covers your rear. just wanted to hear yall's opinion on this. here is the main scenario that you hear: you sell a gun and it is involved in a crime. the last person that is attached to this gun is you. so what happens? i know we do not have to register our guns, but when you buy a new one and do the background check, isn't the gun with serial no. attached to your name and doesn't the ATF have this info.? is the law going to come looking for me? thanks.
