I always thought that to have a LEGAL AR, it couldn't have ANY M16 parts. It is at least a SAFE way to exist. Anyway, the reason I bring this up is I ran across an ad for M16 bolt carriers where the ad description reads

LMT Enhanced Bolt Installed in LMT standard carrier. M16 Carrier. Legal in AR15s with no other full auto parts installed in your rifle. The M16 Carrier adds a little weight. Top LMT quality. Ready to drop in.

M16 Bolt Carriers for AR15s

Legal or illegal????

Understood.

I asked a local ATF Enforcement agent this exact question, and he said there was no way in hell they could get a conviction in court with just a carrier installed.  He said they would need to be able to show that the owner intended to convert the gun to full auto.  With only the carrier installed, this would be extremely difficult to do, and he said it wasn't worth the trouble with the success rate being Zero.  They have better things to do.

That's from the local guy here in Tulsa.....it may be different in your part of the country.

I would imagine if you have an M16 carrier installed, along with a book on how to convert your gun to full auto, and bag of crack in your pocket, it will be a different story.

If BATF agents can't make it fire full auto without major modification or parts interchange - they can't convict...unless you you have angered somebody important in the Gubmint, of course....then it's more like this:

YOU: "illegal auto sear? what illegal auto sear? I never had..."
BATFE Agent "Sir, please come with us"  

Just to clarify for anyone lurking (hehe, put on tin foil hat), I was just curious about the item ad description wording in the original post.

This is what the law says:

3. IMPORTANT INFORMATION CONCERNING
AR-15 TYPE RIFLES
ATF has encountered various AR-15 type assault rifles such as those
manufactured by Colt, E.A. Company, SGW, Sendra and others, which have been
assembled with fire control components designed for use in M16 machine guns.
The vast majority of these rifles which have been assembled with an M16 bolt
carrier, hammer, trigger, disconnector and selector will fire automatically
merely by manipulation of the selector or removal of the disconnector. Many
of these rifles using less than the 5 M16 parts listed above also will shoot
automatically by manipulation of the selector or removal of the disconnector.
Any weapon which shoots automatically, more than 1 shot, without manual
reloading, by a single function of the trigger, is a machine gun as defined in
26 U.S.C. 5845(b), the National Firearms Act (NFA). In addition, the
definition of a machine gun also includes any combination of parts from which
a machine gun may be assembled, if such parts are in possession or under the
control of a person. An AR-15 type assault rifle which fires more than 1 shot
by a single function of the trigger is a machine gun under the NFA. Any
machine gun is subject to the NFA and the possession of an unregistered
machine gun could subject the possessor to criminal prosecution.
Additionally, these rifles could pose a safety hazard in that they may
fire automatically without the user being aware that the weapon will fire more
than 1 shot with a single pull of the trigger.
In order to avoid violations of the NFA, M16 hammers, triggers,
disconnectors, selectors and bolt carriers must not be used in assembly of
AR-15 type semiautomatic rifles, unless the M16 parts have been modified to
AR-15 Model SP1 configuration. Any AR-15 type rifles which have been
assembled with M16 internal components should have those parts removed and
replaced with AR-15 Model SP1 type parts which are available commercially.
The M16 components also may be modified to AR-15 Model SP1 configuration.
It is important to note that any modification of the M16 parts should be
attempted by fully qualified personnel only.
Should you have any questions concerning AR-15 type rifles with M16
parts, please contact your nearest ATF office. Our telephone numbers are
listed in the "United States Government" section of your telephone directory
under the "United States Treasury Department."

All it would have to do is double one time for the ATFE and they own your butt.  You read the law, you decide, is it worth it?

The language there doesn't make much sense.  If you remove the disconnector, regardless of whether you have M16 or AR15 parts installed, the gun can occasionally double.  The installation of M16 parts is not an isolated contributer of doubling/auto fire when the disconnector is removed from either parts group.  Also, the key word there is "and" rather than "or" in the line describing each of the auto parts.  Using "and" in that language effectively construes the assembly of all parts in the group together, make up such a condition, not each part individually installed by themselves.

But I agree, it is not worth screwing with....put a semi carrier in your gun and move on.

Wow, I feel better!

This is exactly why I thought it was a NO-NO. Like I said originally, avoiding the whole thing is at least a SAFE way to exist.

Agreed on the dead horse issue. I was just surprised to see new items being advertised as above. I can see Joe Schmo doing this, but not a business.

There have been NUMEROUS threads on this topic. Look in the legal forums for the sticky on it- its like 9 pages long.

I think hes just venting some...ah...frustration, because the subject has been hashed to death.

Bottom line: Legal? Yes. Recommended? No.

It's also legal to drive with a BAC of .06, but I wouldn't recommend it.

Legal and...

DUPE!

Legal and excessivley duped.

Damn then mine is defective!

Thanks, and,....................................................... I am ready to be drawn and quartered now.
Now if I could just get some assistance trying to figure out what gun Al Pacino used.

All kidding aside, anyone know where I can find ARMS #22 med rings (or similar QD type) AND a Tenebrex ARD 50mm KillFlash from the same source?

you forgot that those carriers AUTOMATICALLY kill all the children in a 100 mile radius.  those are the "smart" carriers, which can break out of gun safes, causing the weapon to go on a killing spree.

man yojimbo... i thought you were tactical.  



have a good one.

Stainless

edit for: spelling

@ $226 a pop plus $hipping .........  The only ones they are helping is themselves.

I can practically pick up 2 FA bolt / carriers at that price.

Legal - yes
needed - no

a pissin match on whether legal or not .......  wait & watch

I'd like to have a nickel for every time this question has been asked!

Can I use an M16 pistol grip on my AR?

Are M16 sights OK?

This thread is a duplicate.
