Is An Assault Rifle Necessary

[jillian]

Now there a loud call to ban assault rifles. Like the AR15 that Nikolas Cruz used to kill 17 people in Parkland, FL. The banners are saying they're unecessary.One person said "You don't need 600 rounds to stop 1 intruder."

That might be true - but what about if you're confronted by a menacing crowd of people >> a gang of violent thugs, MS-13, mafia, organized crime, a mean motorcycle gang, a lynch mob who mistakes you for someone else, or maybe just a bunch of drunk, dopey, street punks.

These all sound unlikely ? Until one of these situations occurs, and then it's too late to think abot the odds of it. A machine gun may be improper as Nikolas Cruz used it, but there are some scenarios in which it would be jsut the right thing to have. In some rural areas, where wolces travel around in

Justification for owning a firearm ...
Has no bearing on whether or not the Constitution has granted the federal government the power to limit one.

States can and do regulate firearms.
It is possible to repeal or amend a previous amendment ... The Constitution allows for those things.

What the Constitution doesn't allow ...
Is the ability for someone to think they have a bright idea, and start legislating a whole lot of crap to suit their desires.

The discussion should no longer be about what someone thinks you should have rights to ...
If Congress can write/pass/ratify the 16th amendment granting them the power to establish/institute the income tax ...
They can damn sure go through the same process if they want to grant themselves the power to decide what or if you can carry ...

.

the only thing not allowed per the constitution, as stated in Heller (which was extremist BS anyway) is a total ban.

regulation isn't prohibited.

The AR-15 is not an assault rifle...it isn't even a military rifle.....a bolt action rifle is a military rifle, a pump action shotgun is a military weapon....the AR-15 has never been used in war, and has never been issued to the military......both the bolt action rifle and pump action shotgun have been used in war.....as have 6 shot revolvers and lever action rifles....

You're really trying there buddy. The M16 is the goto combat weapon for the military, and the AR is a slightly modified clone being sold to civilians. We don't need that slightly modified combat weapon on the street.

The M-16 is capable of automatic fire, the AR-15 is not. The AR-15 is capable of rapid fire, just like every other semi-automatic weapon in the world. I have never seen an AR-15 on the street, and I seriously doubt that you have either. Many normal looking rifles fire just as fast as the AR-15, and also can be fitted with 30 round magazines. Many semi-automatic pistols also have magazines that carry 14 to 17 rounds, and the magazines can be changed much faster.

Although the AR-15 is probably the best home defense weapon available, I don't own one. I know several people who do own one or more of them, and they own them mostly for the fun of shooting them at the range. I have shot them, and they are fun to shoot.

If the next mass shooter uses a Mini-14 or a Glock 9mm, you will want to be banning one, or both, of them next. And, you still will not have solved the problem of mass shootings.

The AR15 is a military assault weapon.

No...it isn't, it has never been used by the military it has never seen military duty.....you are lying.

The 6 shot revolver is a military weapon and has been used in war.

The Lever action rifles is a military weapon and has been used in war.

The pump action shotgun is now, currently, a weapon of war.

The bolt action rifle is currently a weapon of war.

You don't know what you are talking about.

AR 15 Rifle – A Brief History & Historical Time Line

AR 15 Rifle – A Brief History & Historical Time Line

USA -(Ammoland.com)- According to the news media, an AR 15 Rifle is any gun that someone uses in the act of doing something bad.

What is an AR-15 really? Technically speaking, AR-15 is a brand name, like Kleenex or Xerox. And, just as with Kleenex and Xerox, the brand name has been hijacked by the general public to describe a whole class of things.

Who in corporate America asks their intern to “make a photocopy of that document using the Canon copier?” Or at home, few parents tell their kids to “grab a Cottonelle nose cloth before you sneeze!” Exactly. When a brand name is successful, we regular folks tend to commoditize it.

“Hey, will you Xerox the annual report for me?” or “Connor, I’m not telling you again! Don’t blow your nose on your sleeve! Grab a Kleenex!”
The AR in AR 15 Stands for ArmaLite
Before we dive into the history of the modern AR 15 Rifle, we need to look the “AR” part. AR does not stand for Assault Rifle. Or Automatic Rearming. Or even Apoplectic Ruin. It is a product naming convention from the company that invented it, ArmaLite. In fact, there were a number of rifles with “AR” names, like the AR-1, AR-5, AR-7, AR-10, AR-16 and AR-17.

Let’s do a quick review of AR15 Rifle history what got us from conception to where we are today.

1954

Eugene Stoner responsible for early development of the AR 15 rifle.

ArmaLite was founded as a division of Fairchild Engine and Aircraft Corporation. While most people equate the AR 15 Rifle with military variants, the company was actually founded with the goal of developing civilian market guns using modern materials and manufacturing technologies.

The initial business plan called for establishing some success with commercial products, then using that momentum to get into the government and military business.

Eugene Stoner, a former marine and independent weapons designer, becomes Chief Engineer of ArmaLite. Stone meets George Sullivan, Chief Patent Counsel for Lockheed Aircraft Corporation. Sullivan has a super-sized bee in his bonnet about the possibilities of using advanced (at that time) materials like plastics and aluminum alloys in radical new weapons designs. Hold that thought…

1954 – 1956
Plans don’t last long once the action starts… Upon request from the United States Air Force, ArmaLite develops the AR-5 survival rifle. The AR-5 was a modular rifle chambered in .22 Hornet with a four round magazine and bolt action. The receiver and barrel disassemble and can be stored inside of the over-sized stock. This design not only makes the AR-5 waterproof, but also allows it to float. That’s handy for over water ejection scenarios, as downed Air Force pilots were not keen about scuba diving to retrieve their gear. The modern day version of this rifle is the Henry U.S. Survival Rifle made by Henry Rifles.

1955

Armalite AR-5 .22 Hornet Survival Rifle : This “AR” doesn't look much like a mythical “Assault Weapon” does it?

The U.S. Army began a search for a rifle to replace the M1 Garand. While the Garand served admirable in World War II, all that combat use uncovered some areas for improvement. For example, soldiers wanted more magazine capacity than the eight rounds offered by the M1 Garand. Also, weight was an issue, with the M1 tipping the scale at ten and a half pounds. With World War II soldiers carrying their gear for (literally) years at a time, every pound counted.

Front runners in the contest were an updated design based on the M1, the Springfield Armory T-44 and the T-48, which was based on the FAL design.

ArmaLite submits plans for the AR-10 rifle with similar caliber and performance characteristics as the T-44 and T-48. Unlike the others, the AR-10 incorporated radical design changes that allowed use of lightweight aluminum receivers and plastic stocks and hand guards. The key to the design was using a steel barrel extension to lock up the bolt rather than the receiver itself. This allowed use of lighter and less strong materials for receiver construction. The AR-10 weighed less than seven pounds – in theory allowing a solider to carry three extra pounds of ammunition and/or gear.

ArmaLite entered the contest too late in the game to work out new design kinks and ultimately the T-44 was adopted as the M-14 Rifle in 1959. Armalite AR10 Rifle Click here for more AR images
1956
Seeing possibility in the AR-10 design, the Army asks ArmaLite to work on a smaller caliber version to be named the AR 15 Rifle. The project is exploratory, as the military doctrine of the time called for large caliber rifles to be used in engagements at longer distances.

1956 – 1959
ArmaLite sells the AR-10 internationally through a licensing agreement with Artillerie Inrichtingen, the Dutch Arsenal. Not even the Dutch adopt the AR-10 and international sales are light. At this time, ArmaLite is only really selling the AR-5 aquatic survival rifle, so revenue pressures mount.

1959
ArmaLite licenses both the AR-10 and AR 15 designs to Colt Firearms. Robert Fremont, a key player in the design team of the AR-10 and AR 15 Rifle models, leaves ArmaLite for Colt Firearms to help with continued AR rifle development. ArmaLite launches the AR-7 Survival Rifle. The AR-7 was a .22 long rifle caliber rifle targeted at the civilian market, although a number of military organizations around the world bought it.

Colt Firearms sells the first AR 15 rifles to the Federation of Malaya, later to become known as Malaysia.

1961
Eugene Stoner leaves ArmaLite to serve as a consultant to Colt Firearms. At this point, ArmaLite was out of the AR-15 business – for the time being. The United States Air Force tests the AR 15 Rifle and purchases 8,500 rifles.

1963
The Air Force standardizes the AR 15 and designates the rifle M-16. 85,000 rifles are purchased by the Air Force. Also this year, the US Army purchases 85,000 more M-16 rifles.

Colt M16 Semi Automatic Rifle

1965
By this time, the M-16 had become the military’s primary service rifle, with over 300,000 purchased from Colt, now known as Colt's Inc., Firearms Division.

1983
ArmaLite is sold to a Philippine company, Elisco Tool Manufacturing Company.

1987
ArmaLite operations in the US are ended by Elisco Too Manufacturing Company.

1988
Colt loses the government contract to supply M-16 rifles to the military.

1989
Jim Glazier and Karl Lewis of Lewis Machine and Tool Company (LMT), operating a new entity called Eagle Arms, begin producing complete AR-15 rifles for the consumer market. By this time, many of the earlier AR 15 Rifle related patents had expired, thereby opening up the market for complete AR-15 type rifles.

Eagle Arms EA 15 Rifle

1992
Colt, now known as Colt's Manufacturing Company, Inc., enters Chapter 11 Bankruptcy proceedings and a period of litigation.

1994
Mark Westrom purchases Eagle Arms. Colt wins a contract to supply 19,000 M-4 Carbine variants of the M-16 to the US Army and Special Forces Command.

1995
Westrom and Eagle Arms purchase rights to the ArmaLite brand. Within a year, ArmaLite is producing the AR-10B rifle, chambered in .308. During this period, Knight’s Manufacturing produced an AR-10 derivative rifle, the SR-25. Colt wins another contract for 16,000 M-4 Carbines.

Knight Manufacturing SR-25 Rifle

1998
Colt’s wins back the procurement contract for military M-16 rifles with an initial order for 32,000 M-16 rifles. An additional order follows to upgrade 88,000 M-16 A1 rifles to the A2 configuration.

2009 – 2011
With support from the National Shooting Sports Foundation (NSSF), the term Modern Sporting Rifle gains popularity as a more descriptive name for AR-style rifles.

Racks of new Modern Sporting Rifles. The AR 15 Rifle is well on its way to be America's most popular rifle ever.

AR 15 Rifle Present Day
At last count, 16,973,489,012 companies are making AR-style rifles. Actually, I lost count at just over 12 million, so this number is really more of an estimate. Whatever the actual figure is, it's a lot.

So you think that more gun control laws will stop murderers, or they will just not want to put in the effort or ??? What?? Please explain your rationale of using gun control laws to stop murderers/law breakers. Thanks.

There are a lot of proposed "gun control laws." Which one do you want me to speak to?

Any aside from ones we might already have.

Which specifically was I lying about?

We don't have assault rifles, the military does. You can own them but it's not real easy to do.

 

[protectionist]

Yes they are necessary if we`re to maintain our position in the world. We`re number 1!
Report: U.S. averages nearly one mass shooting per day so far in 2017

And if you and your family suddenly found a gang of motorcycle thugs, or MS-13 on your front lawn ? Think the machine gun might be necessary ? Or would you prefer throwing stones ?

 

[BULLDOG]

Yes, I'm sure an assault weapon would be very effective in those situations. Do you think that is the only gun that would have worked?

There are lots of rifles that would work.....and they all work the same as the AR-15, they just don't look the same as the AR-15...the same way a Camry and a Jeep have the same engine dynamics........so if you get the AR-15 you will be able to make a claim on all the other rifles too...since they all work the same........

Sure, but the Camry and Jeep aren't essentially the same, and the parts aren't interchangeable. An AR and an M16 are, and the parts are ALL interchangeable, other than the slight modification to disable select fire.. Do any other guns have 100% interchangeability with the M16 military assault weapon?

--------------------------------------------- NOPE , and thats why the AR15 is needed plus it uses the same military caliber ammunition at this time Bulldog .

Actually any M16 produced after 1986 is illegal for any civilian to own and to get any parts legally one must have a federal permit. So it's not as easy as you think to convert an AR 15 to full auto with M16 parts

Didn't you say crooks don't care about what is legal?

So where are crooks going to get the fully automatic receivers parts but from people with federal permits?

If any idiot gang banger could get the parts then every gang member would have automatic rifles.[/QUOTE]

Don't be silly. You don't have to have an M16 to legally buy all parts needed to conversion an AR15 full auto, except the Drop In Auto Seer. As you can see in this video, the DIAS is small and not very complicated. You could build one that works with a dremel. The only reason fully automatic conversions aren't everywhere is because of the penalty for being caught. Crooks DO care about the law in this case.

 

[protectionist]

We don't have assault rifles, the military does. You can own them but it's not real easy to do.

That wasn't the question.

 

[BULLDOG]

So other than the slight modification to disable the select fire capability, what is the difference between the two?

What you call a "slight modification" is conversion of an ordinary semi-auto weapon into a machine-gun, which easily doubles its lethal potential in a mass-shooting event.

Your question regarding the difference between the two is best answered by the fact that all contemporary armed forces have seen fit to equip their soldiers with full-auto firearm capability. The simple answer is full-auto is substantially more lethal.

The military was presented with lots of guns with full auto options, so that particular feature isn't the reason they chose the M16. Why did they pick that particular weapon, that is essentially a clone of the AR 15?

It doesn't matter what the M16 looks like

There are specific differences in function that make them different rifles.

Other than the trigger group and bolt,which are both legally available without any kind of permit, and the deck height, and an auto sear, what is different?
