Not a good home defense weapon. The 5.56 round like the 7.62 round is supersonic. Meaning it has a supersonic shockwave around it in flight. It kills by forming a cavity in soft tissue utilizing the supersonic shockwave. As the round exits or slows down in the tissue, the cavity collapses. This is what kills the target.
This is what makes this a weapon not to be used in home defense. The amount of energy the round has makes it able to penetrate wallboard and even solid doors. It will rip through most modern building materials and only lose a fraction of its energy. If your wife and kids are in the path of that round, it will not stop to question who it is. It will, without mercy, kill anything in its path.
Get a shotgun instead. You'd be amazed at how bad you can f**k some one up with bird shot and rock salt. And those blast rounds don't penetrate walls endangering innocent bystanders.
In my opinion you made the wrong choice.
