I still have to disagree, not because the AR isn't a more lethal weapon, "I have one also", but rather that having had a home invasion, you don't have time, no matter what you think in your mental scenarios, to get to that closet where your rifle is and get a mag place it in and come out firing. That's not how home invasions occur.
Usually you are near the front door as I was, either going in or about to leave. The door flies open and 5 men came in with 5 weapons all pointed at myself and my live in girlfriend.I was immediatlly hit in the forhead with the gun barrell. I went down, in the first 2 seconds. The constant bickering about things that people refuse to understand about professionals entering your house drives me nuts. NO you won't have time to get your rifle. Especially if it's upstairs in a closet and your wife and kids are downstairs. That's why they keep having this type of crime, because it is so fast and deadlly.
If you can't get a gun into action as soon as that door flies open, you are a victim.
If you knew they were coming it wouldn't be a suprise, you obviouslly could sit there with a bazooka. The problem is that most of us don't walk around the house with an AR.
But many do have a pistol on them. If you can manage to drop the first guy, you may win the battle. Once they make entry and they grab a kid or your spouse, all the theory goes out the window. Then your negotiating skills come into play. The part that we didn't mention, is having a large dog, an alarm and cameras, so they don't come into you life.
Sometimes it's like there are a group of teenagers in here with weapons all over their home, thats not the norm, only a single man can live that way. If you have grandkids, kids, and a wife,sister,etc, you aren't keeping a loaded AR at your front door. The good guys don't always win. It's almost impossible to fully protect yourself from this type of crime unless you live like a monk. Wealthy people spend in the 5 million per year area to gaurd their home alone, CNBC had a story on protecting the rich, this week, just scale it down. At least now we have cameras and alarm systems, back in 1979, we didn't. That made it very hard to protect yourself, along with being in NYC, But even now it happens in heartbeat, you won't have the kind of time to implement these plans once they are in. As I sit here I am wearing a Glock 26, I know I can get to that, I don't know if I would make it 40 feet to my bedroom to get my AR, I highlly doubt it, if they are pro's. Ask an agent or dective, they will enlighten you if you don't believe me.
Obviouslly if you had a choice you would take a rifle every time, but the question is squewed, when you say coming through the door, I take it as though it was a suprise. If you knew that they were coming then a rifle would be in order.
