Full auto regulations in the USA?

auto parts accessory

question by Colter B : full auto regulations in the USA? Most of the weapons are pursued by the recipient. You can buy magazines, spare barrels & all sorts of stuff without the purchase of a “gun” as long as there are no receivers. My question is, when recipients are, what are as a gun, & pretty much all other parts are available as an accessory that makes a trigger group? The difference between an AR-15 & an M-16 is the trigger group. Are full auto trigger groups otherwise provided, that semi-auto trigger groups? Because you can check out accessories without background or anything it seems, could be the trigger group if it change never covered by the trigger group. Or, in this sense in which it is registered, since you are changing the type of weapon? I do never understand this very well, fairly confusing. It seems that it would be logical into make weapons of disc assembly serial number instead of serial receiver length. Please explain. Best answer:

Class 3 weapons are by their sear & / or sear disconnect, 9 of 10 cases it know the sear, in essence, whether you are a registered class 3 are registered sear for a MP5, & you have is 12 MP5, you can use any of the 12 MP5′s do a SELECT fire weapon.The same is true suppressors, register the suppressor , never the gun’s It Going On, that is, in essence here, if you buy a Gemtech 9mm for, it can be on any 9mm you own use, as long as the threads.

    You are pretty close but the receiver for a select fire and fully automatic M-16 is not the trigger group, but the lower receiver, that’s why the Lower receiver is serialized and thats the part that’s registered. Trigger parts are not restricted and can also be purchased without restrictions. AR-15′s and some M-16′s have replaceable Uppers that you can switch back and forth from one gun to another. You can start out with a 16″ 223 carbine barrel and by switching the Upper, make it a 20″ heavy barrel Match gun. The lower remains the same no matter what Upper you put on it. Same serial number, same gun just a different Upper. For the most part AR-15 and M-16 trigger groups are basically the same except for the fully automatic parts thave a sear disconnect that is different from the semi-automatic ones. Any serialized Lower Receiver must be registered regardless,and they cannot be purchased without going thru an FFL Dealer and getting registered to the owner/purchaser. Fully automatic Lowers are subject to Class III Machine Gun restrictions and require a license and background check to purchase. I hope this clear things up for you a bit..

    Yes, It’s very confusing and Inconsistent,

    Actually the difference between an “AR-15″ and an “M16″

    (I will accept and use both of the above terms to mean Semi-auto only and select fire, respectively; without regard to historical accuracy or model designation.)

    Are ; Lower receiver, Hammer, Trigger, Sear(both Semi auto and full) Burst pack parts( if in A2 configuration), Selector, and bolt carrier!

    The lower receiver is the registered NFA weapon in an AR/M16 type weapon.

    The Upper receiver is the registered NFA weapon in a select fire FAL

    In H&Ks it can be a registered reciever, or a registered auto sear in multiple calibers.(9mm,.223,.308, etc)

    Steyr AUGs use a registered trigger “pack”

    It all depends on the exact configuration of the NFA rifle you want to own.

    Bottom line!!!
    If you own 1 Semi-auto AR-15 type rifle, and any components of an M16 (i.e a full auto bolt carrier, hammer, trigger, selector, auto sear, burst pack, Short barreled upper receiver, E.T.C.)

    The B.A.T.F.E will consider you to be in posesstion an unregistered machinegun and you will be subject to federal prosecution!!

    Do NOT F-around, if you are interested in a “Class-3″, NFA weapon contact a local dealer and ask them all the questions.

    Good luck,

    Just one other little thing to add. As best I remember the only trigger group parts that are actually illegal to own (without proper documentation) are the parts that make the m-1 carbine fully automatic. That information should date me a little, and the same may be the case for some newer weapons. Whatever you do make sure you do everything concerning automatic weapons on the up and up.

    The trigger group does not determine if the weapon is full-auto in most instances, the receiver is the determining factor (M1 carbines being the most common exception but you still need ALL the select-fire parts in order for it to work). You can put some full-auto parts into an AR-15 lower receiver but unless that receiver has been modified to accept ALL the parts it won’t work, same for an AK-47, there is more to automatic/select-fire weapons than you think. Select-fire weapons usually have more fire control parts than their semi-auto only counterparts and the receivers are substantially different (in most cases) to accommodate those parts such as extra clearances and holes for auto sears and sear disconnects and the pins that hold them in place. Most weapons cannot be converted safely (or legally) to accept the full-auto parts and that is why there isn’t a lot of concern about the “trigger group”.
    The only legal way to convert a semi-auto to a select-fire is to get a Class II weapons manufacturers SOT stamp from the BATFE, but that license isn’t easy or cheap to get and maintain.

    To Beavizard: Your statement is incorrect about being in possesion of an unregistered machine gun. I have a very early, %100 stock Colt AR-15/SP-1 (semi-auto) that came from the factory with a full-auto bolt carrier, that part alone DOES NOT constitute an “unregistered machinegun”- I’ve asked, the agent said don’t worry about it. They only pursue that if someone has intentionally converted or tried to convert a weapon and they find out about it and/or they find that you have criminal intent to modify a weapon with parts/tools on hand for illegal purposes (i.e. gang members, bank robbers, radical religious groups, postal workers, etc.). The BATFE recognizes that there are a lot of weapons that have full-auto parts in them, examples are the Springfield M1A (semi-auto only M-14) and the FAL to name a few. Those weapons retain almost all their select-fire parts but the receiver cannot accept the parts that are missing and you don’t see the BATFE kicking the doors down to confiscate them and prosecute us – yet.
