I am Concerned about AR15 Home Defense

Summarizing Doctor Roberts' choices results in the following list (make sure to read about the importance of barrier penetration just below the list):

...and brush before bed. Your source is a dentist.
 
Actually, I personally prefer to use #4 shot in 12 gage. It still seems to have great wound potential in across the room distances, and does not seem to carry a killing payload, after hitting and going through a wall.

Yes, and very well qualified in the firearms wound field. He worked with Dr. Fackler until his retirement. Here are some more facts about Gary Roberts.

About Gary Roberts
Dr. Roberts is currently on staff at a large teaching hospital and Level I Trauma center where he performs hospital dentistry and surgery. After completing his residency in 1989 while on active military duty, he studied at the Army Wound Ballistic Research Laboratory and became one of the first members of the International Wound Ballistic Association. Since then, he has been tasked with performing military, law enforcement, and privately funded independent wound ballistic testing and analysis. As a U.S. Navy Reserve officer from 1986 to 2008, he served on the Joint Service Wound Ballistic IPT, as well as being a consultant to the Joint FBI-USMC munitions testing program and the TSWG MURG program. He is frequently asked to provide wound ballistic technical assistance to numerous U.S. and allied SOF units and organizations. In addition, he has been a technical advisor to the Association of Firearms and Toolmark Examiners, as well as to a variety of Federal, State, and municipal law enforcement agencies. He has been a sworn Reserve Police Officer in the San Francisco Bay Area, where he now he serves in an LE training role.
 
There is a gun for every purpose. IMO, an AR is not a practical home defense choice, unless your surviving an apocalypse or live in a war zone.
It is however smart to have one+ in case of those and ...trying to see who hit the coke can at 200yds between you and your 12yr son(whomever) at the range is down right fun and gets you in sync with the weapon. Again just an opinion.
 
Great, except for penetration...

I would HAVE to have bullets that were made not to penetrate. I saw where a 9mm went through several walls. I would have an AR type rifle chambered in something with a wider choice of bullets and ammo.

To me, the ideal home defense gun would be a 9mm carbine.
 
Boy, has someone ever been telling you some whoppers!

While suppressed AR 5.56 shorties are not "hearing safe" they are much quieter than unsuppressed ARs. They don'y fry suppressors.
Specifically, I was told that nobody warrants their suppressor in a 7.5" in 556 because of the high probability of frying them with repeated use? Not so? How many rounds do you have through your 7.5 suppressed barrel?
 
You said AR pistol, not 7.5" barrel. Most 5.56 AR pistols (and SBRs) have 11.5" barrels. Few have 7.5" barrels because of velocity & reliability issues.

You are correct that many 5.56 suppressors are not rated for 7.5" barrels. They are usually rated for barrels 10.5" or more.

I've got a couple thousand rounds through my suppressor, but it's used on 11.5" uppers.

Oh my goodness, goodolboy, asked the simple question about whether or not the AR-15 with .223/5.56 ammunition was sufficient for home defense and what we devolve to is a discussion about whether or not he needs to use a silencer.

Can't anyone stick to the point?

The bottom line is, yes, the AR-15 loaded with 223/5.56 ammunition is adequate for self-defense. It can, under appropriate circumstances, penetrate a wall made solely of gypsum wallboard., but is unlikely to penetrate further with lethal effect. No guarantees can be made, but an AR, from the available tests, appears no more dangerous to people in other areas of the house than other riflers or handguns that might be used in its place,
 
OK here's what a Veteran (some of you fellas call libtard) thinks.
No single weapon make the perfect home protection. But this is what we do. Pistol grip 20gauge shotgun. The first load is birdshot. After that 00. Next a 9mm high capacity. XD here, but thinking about a full-size S&W 9. AND a SIG 320 or 365. No .45 cuz if Mrs. grabbed that it's end up on the floor. Just bites to hard for her Actually made up my mind. NEXT an AR15.
carbine. But that's not home defense. Well unless the streets break out in craziness.

Bottom line here.
1 easily concealed Model 37 daily carry
1 M&P 9 high capacity
1 870 pistol grip 20G
1 AR15 soon an M&P

BTW libtard pacifists in country (VN) were always the first to go full auto.

AR15's are for plinking .
They look cool and are fun to shoot. But unless your about to get overrun by rabid coyotes or armadillos, a 870 12 guage is the way to go. Nice 18" barrel and 2 shot extension tube, and you're all set. Go with a youth size length of pull like 12" though.
 
The suitability of any long gun for home defense is situationally dependent. It may better than a handgun in certain circumstances, but the handgun covers everything. My AR and 870 got sold a few years back after I decided it was pretty much unnecessary and I don't miss them a bit.

A member on another forum criticized that decision and said I should look into training with and seeking advice from people like Chris Costa, since I obviously didn't understand the application of long guns and the AR specifically. I did some googling and came across the following video. Although primarily discussing the merits of handgun vs shotgun, he does mention M4's and I think a lot of the points he makes regarding shotguns apply to any long gun.

This old thread seems to have arisen phoenix-like from it's sleep.

I helped with investigation of a police shooting in town in a trailer park. The decedent was hit in the head with 5.56 M93 ball; that bullet, the second and third fired from a 20" barreled AR-15 completely penetrated three exteriorior trailer walls and a roof before continuing on somewhere north, never to be recovered.

Later, in a different agency, we purchased 40 grain SP for AR-15 A3's for our entry team to reduce that potential, but even those light, soft rounds would completely penetrate most walls, often two or three walls.

FWIW a motorcyclist emptied a 9mm (FMJ bullets) into our Silver City office (standard frame construction) after it closed one night; file cabinets and a VCR stopped most bullets, with some penetrating two walls and stopping at the far hallway wall.

If you fire inside a house, you need to be sure there's really no other choice.

A good 12 gauge loaded with #4 buckshot is what you want if you are conscerned with not only protecting your neighbors, but also increasing the effectiveness of the weapon.
 
I wonder why the FBI would go through the trouble of publishing a white paper that says the 5.56 carbine is less dangerous to innocent bystanders than pistol rounds or buckshot/slug rounds. Strange.

The self loading magazine fed rifle with 30 rd mags is the superior home defense weapon to all pistols and shotguns. Period.
