GUN Enthusiasts, Come!!

Except for the fact he might end up shooting his neighbor instead of the intruder if he was to ever use it for protection.
Do you have any examples of where this has happened in a self defense shooting? I've never heard of one.

According to the tests done by the BoxOtruth, anything more powerfull than a .22lr is capable of penetrating multiple layers of sheet rock. Including all defensive pistols, rifles and shotguns.

 
If your really worried about overpentration the AR15's light high speed round has the greatest tendency to disintergrate after the first 1-2 layers of wall board. It gives great primary performance against bad guys (even body armor), then fragments into many tiny pieces that quicly loose thier energy. Most handguns, including 9mm, will pentrate many more layers than an AR15 with 55gr FMJ ammo.

Of course, you won't find an AR15 for under $200.

 
I think an AR is a little extreme for home protection. I have a Mossberg 12ga and a Springfield XD40 for home protection.

And I have used the XD in defense of my home when I lived in Reno. I prefer the coverage of the shotgun but the pistol is advantageous when trying to be stealthy and catch someone.

 
Do some research on that gun, it caught my eye for its small size and decent price. However reading up on it, there are numerous cases of a failure of some sort on the sldie after 500+ rounds have been shot through it. I started to get it anyway since the purpose I would use it for would never see that many rounds but something about buying a gun you knwo will fail didnt seem to smart to me.

ftw, overkill maybe

Why? More extreme than a 12 gauge shotgun?!!!

The AR has less danger of overpenetration that either the shotgun or the pistol, with the added advantage of penetrating body armor, 20-30 rounds on tap and devestating ballistics against 2 or 4 legged critters. Not to mention the ability to use silencers to protect your hearing.

The AR15 is the ideal Homeland defense rifle. Suitable for all occasions.

You're kidding, once again. . . . . . . right?

Here, you want to quote the box O' truth, here's results. 12 pine boards (keep in mind, tougher than sheet rock) didn't stop a .223 round.

Here's the link for the rifle/handgun testing - http://www.theboxotruth.com/docs/bot1.htm

Here's the link for the shotgun testing -http://www.theboxotruth.com/docs/bot3.htm

1. Notice that the #4 and #1 Buck penetrated 6 boards. In previous tests, 9mm, .45 ACP, and M-193 out of an AR all penetrated all 12 boards.
Not to mention, I highly doubt an intruder is going to be wearing body armor on a regular B&E.

The average for shots fired in a home defense scenario is 2. Unless you plan on going to war with a gang, 30 round clips are completely unnecessary. If you can't hit your intruder within a few shots at point blank range, you shouldn't even own a gun because that clearly shows you don't devote the time to practice.

And finally, a silencer is also completely unnecessary. You'll only get a couple shots off, and you know **** well you'll have fired more than a couple bullets at the shooting range before this hypothetical scenario.

Please, just stop already before you put your foot further into your mouth. There is no real justification in using an AR-15 for home defense unless you live out in the boonies.

no, the m60 is the ideal home defense rifle. unless of course, you can handle a handheld minigun.

are you really so ignorant as to believe that an ar15 has the penetrating power to go through a bulletproof vest... but yet it wont go through walls? think man, think.

good thing the ar 15s 223 round isnt more powerful than a 22lr //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I was mistaken. It was the AmmoOracle, based on FBI testing:

Q. Don't I have to worry about FMJ rounds going through walls and hurting my family or others? You always have to worry about it, of course, but even FMJ 5.56 rounds will have less wound potential after penetrating a wall than even 9mm handgun rounds. Generally after passing through an interior wall or two, 5.56 bullets will have lost enough velocity that resulting wound damage would be greatly diminished. It should be noted, however, that all of the above bullets are still potentially deadly to those on the other side of a wall, so plan accordingly. Interior walls are concealment, NOT cover.

Fact: Evidence increasingly shows that 5.56 FMJ rounds like M193 and M855 are not the over-penetration risk they have often been though of as. In interior wall tests, 5.56 rounds have less wounding potential after wall strikes than any common 9mm or above handgun ammunition and/or 00 Buck shotgun loads.http://www.razoreye.net/mirror/ammo-oracle/AR15_com_Ammo_Oracle_Mirror.htm#fbispec

M193 and M855 at anything greater than 2200 fps will generally defeat all body armor up to and including Type IIIA. How much damage those rounds will do AFTER penetration is guesswork. In shorter barrels (14.5" and below) that damage is likely to be limited and wound profiles in such instances will resemble .22LR hits. With higher velocities it's still hard to imagine explosive fragmentation at anything but point blank range but M193 and M855 will certainly defeat all soft armor.http://www.razoreye.net/mirror/ammo-oracle/AR15_com_Ammo_Oracle_Mirror.htm#fbispec
The reason for this is the .223 is a light, very fast round. It does great damage and can even penetrate body armor, but it fragments easily after hitting a hard target. These fragments loose velocity very quickly. A min 16" barrel is needed to achieve fragmentation velocity reliably. The common 14.5" barrel on most M4gery's do not reliably achive the needed velocity.

Q. Isn't 5.56 too dangerous to use indoors? Shouldn't I use a pistol or shotgun instead?
Virtually any kind of ammo, with the exception of light bird shot, will easily penetrate typical wall construction (two layers of wall-board separated by 3 to 4 inches of space). Testing has shown, however, that after penetrating a typical interior wall, a 5.56mm projectile will have less wounding potential than most common handgun or buckshot loads. This is true because the low mass of the bullet sheds velocity quickly, and velocity is its key wounding component. This doesn't mean that 5.56mm ammo isn't still potentially deadly, but that the severity of an injury is likely to be less from a 5.56mm bullet than from a 9mm, .40, .45, or #00 buckshot round. What is important is not the degree to which these rounds penetrate, but their "ex post lethality" or their lethality AFTER encountering wallboard or other cover/concealment.

The difference is so significant that the FBI and other ballistic experts recommend that law enforcement transition to handguns to "dig suspects out" of cover because of the superior penetration and wounding ability of handgun rounds over 5.56 or .223.

This, along with the increasing number of lawsuits from "friendly fire" submachine gun victims and 5.56mm's ability to penetrate ballistic vests, are some of the reasons that many SWAT teams are transitioning away from the 9mm MP5 and selecting 5.56mm carbines instead.

This is understandable given the longer barrel length and therefore higher velocity and consequently higher penetration of handgun rounds in submachine guns.

If our experience on the forums are accurate, most shot gunners and submachine gun fans receive this news poorly. It does seem counterintuitive since 5.56mm is a "high powered round." All we can say to this is that the FBI FTU fired hundreds of rounds through carefully constructed wall sections and then into gel. Ignore these results at your own peril.
Fact: Interestingly enough, in FBI Firearms Training Unit tests show that submachinegun and handgun rounds penetrated more on average than .223/5.56mm rounds in typical interior construction and tissue. Opinion: Generally high velocity rifle rounds fragment so readily that over-penetration in an urban (indoor) setting is LESS dangerous than with handgun or submachinegun rounds like 9mm, 10mm, .40S&W, etc. 5.56 FMJ rounds will do more penetrating than JHP and JSP rounds but still are generally safer for interior use- insofar as bystanders are concerned.

I can find plenty of news reports of home invasions where bad guys use body armor, but none where the home owner killed a neighbor while firing an AR15 in self defense.
