    Yes, it'll work. No, I don't think it's legal. It would be trying to make a fully automatic firearm.

    I rush in where others flee.

    you can't make a full auto by just subsututing a M-16 bolt carrier
    as there are a lot of ar15s that have M-16 bolt carriers I don't think that is a problem.
    just don't go to messing around with the sear and there should be no problem

    DO NOT INSTALL ANY M16 PART IN AN AR-15 TYPE RIFLE! ITG, there is a special section in the Federal Firearms Regulation Reference Guide that spell out in very clear tems that the use of ANY of these M16 parts in an AR-15 type rifle is prohibited: Hammers, triggers, disconectores, selectors, and BOLT CARRIERS. These parts may only be used if they are modified to AR-15 type- a machining job.

    There are no legal AR-15 rifles which use M16 carriers. The older AR-15 carriers were much closer to the look of the M16 unit than they are today, but there were differences. There is no point in discussing the auto-sear because if the receiver is drilled to accept it it is a machinegun no matter what type parts are installed. Many later Colt rifles will not accept an M16 carrier due to a block installed in the lower receiver. Play it safe and stick with the semi parts.

    A very good point (as always) by Mr. PIG. When this ruling went into effect dealers and manufactures were sent a sheet by the BATF which showed drawings of the 5 M16 parts and the same parts built to AR-15 specs. The differences between the parts is odvious. I'm sure that you could request a copy of this list with the drawing from the BATF.

    What was once legal suddenly become illegal and if you have an early AR type rifle made by one of the companies listed in the ATF guide: Colt, Eagle Arms, Sendra, SGW, Quality Parts (Bushmaster) and others, you will have to either change the parts your self or return the rifle and have the manufacturer install the correct parts. All of them, if still in business, would do it if they manufactured it that way originally. They won't touch it if someone else made the changes before you bought it.

    Now before we get the usual dozens of posts screaming about the BATF and their draconian rulings you need to be aware of the facts behind this. FAR too many people were installing these 5 parts in their AR-15 rifles (if not already equipted ) and then buying a "drop in auto sear" or something like it and making their own machineguns- usually without paying the $200 NFA tax. This was just like the old days with silencers- you bought a tube from one supplier and the internal parts from another- sometimes even at different gun show tables. That came to a stop pretty fast as the BATF declared ALL silencer parts to be silencers. Just too much abuse.

    In 1986 the manufacture of machineguns by private individuals was banned by congress and a ruling came down from the BATF that ONLY NFA registered AR type rifles could have those 5 machinegun parts installed. I thank SaxonPig for bringing this up as it is an important part of the discussion.

    Thanks Guys!!!!! I just bid on a AR15 Bolt carrier, and won. Then today I got a letter from the guy that had it in the auction.. He said he was sorry, That he had sold the AR15 part, and would send one for the M16... I told him I had to check into to it, I thought it was not legal, Just could not remember. THANKS AGAIN!!!!!!!!!!!

    It will hurt you, More than it will hurt me..

    so... the ar-15 is the civilian model of the m16, aside from size... wtf is the difference. Also is there any civilian model of the MP5?

    AR-15 is a semi-auto only.
    SP89 is semi-auto version of MP5, but without a buttstock.

    I agree with MC except for the implication that Colt installed some M16 parts in some AR-15 rifles. I do not believe that to be the case. It was common with the early clone makers, but I do not believe Colt ever did it. Early in AR-15 poroduction, Colt took steps to prevent full auto fire, and installing any M16 parts would be counter to that goal.

    It is interesting to note that very early AR-15 rifles had bolt carriers and hammers much different from later rifles. The early rifles did not have the notch in the hammer and the corresponding sharp edge on the bolt carrier to catch and jam the hammer on the bolt carrier if not caught by the disconnector. With the early setup, apparently removing the disconnector and loading ammunition with soft pistol primers would allow the rifle to fire automatically because the hammer would have enough energy when following the bolt closed to ignite the primer.

    This technique is rumored to be used by the ATF when finding an AR-15 with M16 fire control parts, but no auto-sear. If the M16 parts are in place, but no auto-sear is present, the rilfe will usually fire full auto with soft primer ammunition. If it does, the charge of an unlicensed machine gun can be brought.

    JudgeColt, Your honor- you are of course correct about Colt never using any M16 type parts in their AR-15 rifles. As we know, Colt was the manufacturer who developed the semi-auto AR-15 concept and modified the parts accordingly. I was however quoting the manufacturers list directly from the BATF General Information, items of interest section. Colt is the first name mentioned on the list and I felt I should not edit it out in my post, just in case anyone felt I might be inventing some of this information I tend to force on people! I like to have a solid source if questioned.

    Thank you however for pointing this fact out as a buyer of a Colt Ar-15 can feel confident that his rifle left the factory fully compliant.
    Whether or not it still remains so is a different issue! By the way, as I once told you, I am still anxiously awaiting the day when I can tell you something which you don't already know. That day may some day come, but I think it is FAR in the future.

    You are in violation of Federal laws if you even OWN one of the parts it takes to make a semi-auto AR into a select-fire conversion, if you happen to be so unlucky as to also own an AR receiver, whether the select-fire parts are installed or not! You can own some or all the parts quite legally - believe it or not - as long as you don't also own a receiver into which they could be installed. With the current political climate taking the direction it's headed, with regard to firearms in general & semi-autos in particular, woe be to them who get caught with what the Fed rules they shouldn't have in their posession.
