Yes it a very good point - the AR also a very poor choice for intrusion defense- btw a shoot gun makes a good club and you old military guys know how parry and thrustHow close are neighbors? A shotgun at home defense ranges has a pattern about the size of a half dollar so don't think you can't miss with one. Asked about neighbors because with handguns or rifle that bullet will go through and through. If I made a shot down the hallway and missed that bullet is going to end up in the neighbors house. Hell if I connected it still could go through.
