Difference between M16, M4 carbine and AR 15?

If you don't know the answer you probably shouldn't own a firearm.

Lots. Do some research.

2 goes ratatatatat!

1 goes bang bang bang

OK?

It's a libtard guys

Technically all rifles can be classified as "assault rifles" depends on who gets to pick and chose, composite accessories are the current thinking (Armalite) AR means Armalite Rifle, where as M means military but the 15 and the 16 are basically the same. the M4 uses different ammo

All are excellent for wild hogs.

THIS ^^^^

AR-15 doesn't have the fun selection!

They are all Stoner design AR15s. The M16 and M4 carbine have the original Stoner lower reciever internal dimensions allowing for a select fire auto sear. The civilian AR15 has those dimensions altered just enough to not allow for the Standard AR15 auto sear to be installed with the trigger group.

2 is where its at!

Ha! Ha! Probably true.

In simplest terms M16 is a military grade 5.56, M4 carbine is a short barrel version of M16 and AR15 is a civilian knockoff of an M16--some quality, some not quality.

Thanks guys. For the smart asses. I appreciate the satire. Lol.

Reason I am asking is because I want to purchase one and uphold my second amendment rights and support my president in case they try to force him out of take our nation hostage.

What is a good quality brand that wont breakdown,something that will last.

Is FN 15 a good brand?

Fucking Retard is giving us AC's a bad name.

You dumbass. M4 does not use different ammo.

Agree

The AR15 game is pretty tight now-a-days. Even budget ARs are well built. You can get a quality AR for right around $500 now-a-days.

If might not have all of the bells and whistles or look all tacticool, but they're going to function just fine and last for any foreseeable use if you take care of them. Sometimes you might need to upgrade some of the little parts after a lot of use, but that's very inexpensive to repair.

You can also upgrade your cheaper AR and make it just as good as any expensive one little by little as you learn more about your rifle, which can help by distributing expenses out over a longer period of time.

Whichever way you decide to go, and AR 15 is a great purchase. Parts and ammo are EVERYWHERE!

That's also one of the reasons I buy 9mm. The ammo is fairly cheap and very common.

Depends on what you want to spend? I like M&P15 Sport 2 for the price it's hard to beat! DPMS makes some good lower end
and Rugers Version of the AR gets good marks! Springfield has their version called "SAINT".

I believe Colt has the right to the name "AR-15" so you'll see all the other using something similar like Anderson's AM-15.

Spend some time on YouTube plenty of AR videos there!

M16 has a selector switch that allows the operator to shoot 1 bullet per pull of the trigger OR select automatic so 1 pull of the trigger multiple rounds. An M16 is a pretty basic rifle too, has iron sights, MilSpec has higher standards for parts so the rifle is a bit more rugged for sustained military use. It's a very standardized platform meaning one is just like the other.

An M4 is the same basic build as an M16 but with a shorter barrel and adjustable stock. So it has a selector for full auto as well.

An AR15 is SEMI-AUTO only rifle (1 pull of trigger = 1 shot fired), it's quality and specifications can be MilSpec but there are also variations. The materials used to build them can be cheap too. For example, there are carbon fiber version that are very lit but would come apart over time in real combat situations. The AR is chambered in a WIDE range of ammo types. I personally have a .223 (just one thousands of an inch bigger then a 22 rifle), 450 bushmaster and 308 winchester. M16's and M4's are not found in ANY of these calibers. There are other AR's chambered for 300 blackout, 9mm, .22, .45 .357 and .5 or 50 caliber just to name a few more.

I'm equally lethal with my AR as I am with my shotgun and handgun (Just ask the deer out back), its really just a difference in the range at which I need to engage, if it's close up, shotgun or handgun is probably better but at longer ranges, a rifle is where it's at.

Anyone conflating these concepts is simply trying to manipulate you or are just plane ignorant themselves, either way, if you want to understand, asking questions is smart, just be sure to qualify who's giving you the info.

For me, avid hunter, former US Army Infantry officer and BRM instructor and gun owner for over 45 years.

Oh, and a note for the picky out there Some M16's and M4's do not have a full auto function, only three round bursts. But that's probably too deep of a discussion to sort out in this forum.

I disagree.

As long as you know basic firearm safety, you're good.

Learn a bit about firearms, talk to some local gun dealers and see what they have in stock, hold a few to see how you like em and buy one. Once you own your first firearm, they become addicting. You'll learn a lot more about them having one than not.

PSA...Palmetto State Armory!

You can use a heaver load due to shorter barrel...am I wrong on that?

right here is the type idiot that you don't want to listen to.

In this day and age, with the advent of CNC machines EVERYFUCKINGWHERE the "spec" tolerances on just about all of them will be just fine.

One "name" is really not any better than the others.. trust me, I've been dealing with these things for 40 years, Hell I was making M-16s out of AR-15s before FOPA.

Want an expert opinion?.. here it is. Buy the one you like, just open it up, look inside the receivers for ugly machining marks first.. if they are there, hand it back.


Next, buy a nickel boron bolt and carrier and fire control group.

Those are the best upgrades you are going to do to have a reliable gun in any configuration.

there ya have it.

FN as in Fabrique Nationale Herstal?

Yeah, quite good.

Here's a catalog of variants in the 5.56x45mm variety: [link to www.tombstonetactical.com (secure)]

AR10 uses the 7.62x51. There is a slight difference between 5.56x45 and the .223 but that's a velocity difference and not a physical one. M4,m16,ar15 are all the same caliber.

Yes, but you can use a heavier load in the M4 because of shorter barrel length. I did not say different ammo size/caliber.
