I am new to this post and have a friend that owns a M-14 with selector lock manufactured by H & R. Is it legal to own this weapon? At gun shows I have been told that as long as you don't try to sell the gun or shoot it full auto its not illegal and you can bring it to gun shows as long as it has a selector lock. Also on the internet, I located a couple of cases where M-14 owners went to prison for trying to sell M-14s. Other people have told me its illegal to own an M-14 since they were never issued by the military and its worth 10 years in the pen if you have one in your possession. Do any of you guys know what the real deal is on this?
