Ok I see a lot of these online for sale. All with a single shoot set ups and mag locks (California compliant). This is how they are sold. Now after I get it home. Can I then legally replace the single shoot mag for a ten rounder. Still keeping the mag lock in place and be legal. I under stand AR's,AK's and the 556's are all different. AR's need to be dedicated pistol lowers and never be made into a rifle. The same is not a issue with the other two. What are the pros and cons of ether. Along with the legality of changing the mag out.
PLEASE HELP ME TO DECIDE???
