Most homeowners use handguns, and it's only been recently that the younger generation has adopted AR actions as their first line choice.
So, finding a case in fact is going to be difficult. That doesn't mean it shouldn't be discussed. BTW, the guy who used a shotgun and put some rounds thru the door didn't turn out so well, despite the VP's assurances it was a good method.
The issue is whether many even consider using a short barreled rifle at all, and the costs do come into play.
So, don't. Paying the stamp to force you to treat an AR as a rifle with all the loss of CCW use needs consideration. Rifles don't enjoy a lot of freedom compared to a CCW pistol.
Consider the alternative, the AR pistol. Exact same weapon in terms of ballistics, it just doesn't have a stock. At HD ranges accuracy isn't an issue. What many need to consider is how to use the weapon with it's specific issues to fire it accurately.
It's not a fact they must be held in some way against the shoulder, either. Holding it close across the chest with the sights held to eye level works, too. Adopt a shooting posture that enhances that specific gun's issues and learn to resolve them.
Entirely why I am building an AR pistol - the added benefit is that in my state I can use it in the Alternate hunting season where a rifle isn't allowed. Further, I can transport it and carry it the same as a handgun. A rifle has anti poaching restrictions against it. Some in other states can have truck guns ready to hand, in my state it's very questionable and leads an LEO to considering further charges. Very bad juju during hunting season to be cruising around with a loaded rifle in the front. It's called road hunting and it's illegal.
But a pistol in a case concealed ready to hand, not so much legally. If traffic stopped its really no issue here, just inform the officer by handing him your CCW license, done. What you carry will likely not even be mentioned. Plus you can transport across state lines at will, with a stamped SBR you must be in possession of ATF written permission, which at best must be renewed annually.
At home, all the benefits of a SBR without the legal entanglements of being an approved firearms possessor registered with the ATF.
So, yes, a short barreled weapon does have a lot of advantages, even more if it doesn't have a stock. And at HD ranges, the AR pistol is more than accurate enough.
Which leave the noise suppression issue still to be dealt with. It does need some solution.
The worst case scenario often brought up is someone breaking into your house while you are sound asleep. You struggle to awake, get up, grab a gun in the dark, and do what?
Dozens of different life threatening scenarios are always brought up, by the same guys who advise you on the legal liability of your deadly illicit weapon meant to deliberately maim a lost soul returning home from their drunken evening.
Yeah, sure.
I see it as a lot of other things not being done right to prevent it in the first place, you don't just wake up with a knife at your throat and your wife being accosted.
You will hear someone trying to defeat your defenses, and you should be more than past the point of calling 911 and securing your bedroom before they even get to you. Try installing some motion sensors and alarms before spending all the money on an expensive high dollar firearms solution to address the worst case scenario.
Keep a set of electronic earmuffs with the gun and call it good. $80 vs $200 +$800 for the suppressor + Trust fees + etc etc etc. Be that as it may, in my state you can use it for hunting, so, some justification for the cost exists. Or you could just use the e-muffs with the gain up to hear even more.
Goes right along with your infra red cell phone back for finding game. I could buy muffs and the I-reader for less than a silencer and have a lot more utility. At least I will see why my heating bills are up.
On gun forums you get a lot of gun centric solutions, but the reality is that HD is not gun solved, a gun is the tool of LAST resort and if you have other things should have been done or it's going very badly - which are even more extreme odds than a home invasion in the first place.
Lets get honest about it, if you are really worried about home invasion, you should have your home armored up to the point even the local SERT team knows they can't get in. NOBODY discusses that as the first option, they go straight to using a gun because you are forced to accept their last resort scenario.
It's all about internet one-upmanship, not a logical risk assessment of what could actually happen and where you need to improve your security.
Given the odds, don't steal your drug lord's stash or his girlfriend, and you have eliminated 95% of the risk.
That leaves a few other issues like leaving your doors unlocked, or opening it after dark just because someone knocked. Well, duh, did you not look to see who was there?
NOooo, we can't exercise common sense, you always wake up to a knife at your throat and your wife being accosted by leering thugs. Well, move to a different neighborhood, get a dog, and get a life already.
Keep your mental video in check and assess what's really going on. We did have a gang of thugs locally invade two homes last week. The first was a mistake, broad daylight, they left when they figured it out. Reading between the lines, the homeowners opened the door and let them in.
Second home one was killed on the spot. Stolen property was involved, the investigation is ongoing.
Don't take property from others, or their GF, and don't open the door to just anyone. Start with the basics and then when you finally get to what gun to use, you will likely know exactly what you need for that specific set of circumstances.
I wouldn't want to be the guy trying to get in.
