The ARFULLAUTO Kit is provided for educational purposes ONLY!
Its purpose is to give you a complete and working knowledge of what it takes to make an AR-15 operate in full-auto mode, which should give you a greater understanding, appreciation, and working knowledge of the AR-15 platform, in general.
The kit, as-sold, cannot and will not make or allow an AR-15 to operate full-auto, (a 30-second modification of the kit with a pair of pliers, with no modifications to an AR-15, itself, would be necessary for that to occur) but all of the information specifying how to modify the kit to do so is given, in order to provide you with a complete knowledge of several intricacies of the AR-15 platform.
Though we certainly do not recommend modifying the kit from its as-sold state, what you do with the kit is YOUR business; however, the kit could be modified to make an AR-15 operate in full-auto, which would likely be illegal in your jurisdiction, if actually done, so for obvious reasons, we recommend using the kit only for its stated educational and informational purpose.
The kit,as-sold, cannot and will not make an AR-15 operate full-auto. Modification of the kit (with a pair of pliers and about 30 seconds) would be necessary to create the parts necessary to do so, which would likely be illegal in your jurisdiction.
The ARFULLAUTO Kit includes the following:
- Completed Bolt Carrier Group Counter Weight (BCGCW) and detailed instructions for installing the completed part. This part would only be used with a Semi-Auto bolt carrier to create the functionality of a Full-Auto bolt carrier. A Full-Auto bolt carrier (legal to own by any civilian, despite its name) would not require this part, though the part is included in every kit for visualization of how to adjust the correct timing, necessary for full-auto operation. This part is not illegal to own, even in its completed state, because it cannot and will not make an AR-15 operate full-auto, unless paired with some other part that, in and of itself, is considered a machine-gun part (and therefore illegal to own).
- Trigger Control Group Travel Reducer (TCGTR) material, which is cut to the correct form and specifications -- including detailed instructions for making each of the four bends in the material, necessary to create a fully-functional and completed part. The instructions include a diagram and layout that could be used to determine when a fully-functional and completed part had been formed correctly. Because the part is not completed unless and until you make the final bend in the metal material, the kit, as-sold, is legal to own; however, modifying the kit to create a fully-functional and completed part is likely illegal in your jurisdiction, since the completed part, alone, when added to particular stock AR-15s, may cause them to operate full-auto, and thus would be considered, by itself, a machinegun. To make a fully-functional and completed part, you would need a pair of pliers, such as 8" Lineman Pliers.
- The kit includes a second set of TCGTR material you could use for practice in making one or more bends in the material, while retaining a completely unmodified set of material for other insights and education.
- Detailed instructions and troubleshooting information for both parts (available online, using your Order Number and PIN, when your kit ships).
- Everything necessary for a full and complete understanding of how to make an AR-15 operate full-auto, including the materials necessary to create fully-functional and completed parts, for those who learn better by tactile observation.
Note: The kits are legal, as-sold, because only the materials necessary to create a fully-functional and completed TCGTR are included in the kit, and not the fully-functional and completed part, itself. Modification of the kit (using a pair of pliers and about 30 seconds) would be required to create a fully-functional and complete part, and we don't recommend doing so. The TCGTR can be fully-formed in a matter of seconds, by correctly bending the material, as detailed in the instructions, though actually doing so would likely result in a fully-functional and completed part which would be, for all intents and purposes, illegal to manufacture or possess in most jurisdictions.
To install the completed parts, you would need a Phillips-head screwdriver and approximately 30 seconds.
The only requirement for converting back to semi-auto, would be to pivot the Upper Receiver up, remove the drop-in TCGTR, and pivot the Upper Receiver back down. (Always clear your firearm of any ammunition before installing or removing any parts.)
This means you can legally keep these kits, as-sold, on-hand without fear of possessing illegal parts.
Creating a fully-functional and completed TCGTR part from the materials provided may be considered by law enforcement to be an illegal part or combination of parts, (and therefore an unregistered and illegal machinegun) so we suggest you be extremely careful and cautious about the laws that may or may not apply to you, including the National Firearms Act if you reside in the United States. For this very reason, though the instructions provide complete information on how to do so, we do not recommend modification of the kit, as-sold.
Please keep in mind that we are not your attorney, and providing legal information is not the same as giving legal advice. This page includes legal information, but we cannot and will not provide you with legal advice.
Though we cannot begin to tell you all of the laws concerning machineguns in all jurisdictions, below is some information that may be pertinent to those within the United States and similar jurisdictions, including WHY this kit is legal to buy, sell, and possess.
In the United States, the Gun Control Act (18 USC Chapter 44) and the National Firearms Act (26 USC Chapter 53) control the definitions relevant to machineguns, as follows:
- 18 USC 921(3) - The term “firearm” means (A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon; (C) any firearm muffler or firearm silencer; or (D) any destructive device. Such term does not include an antique firearm.
- 18 USC 921(4) - The term “destructive device” means— (A) any explosive, incendiary, or poison gas— (i) bomb, (ii) grenade, (iii) rocket having a propellant charge of more than four ounces, (iv) missile having an explosive or incendiary charge of more than one-quarter ounce, (v) mine, or (vi) device similar to any of the devices described in the preceding clauses; (B) any type of weapon (other than a shotgun or a shotgun shell which the Attorney General finds is generally recognized as particularly suitable for sporting purposes) by whatever name known which will, or which may be readily converted to, expel a projectile by the action of an explosive or other propellant, and which has a barrel with a bore of more than one-half inch in diameter; and (C) any combination of parts either designed or intended for use in converting any device into any destructive device described in subparagraph (A) or (B) and from which a destructive device may be readily assembled. The term “destructive device” shall not include any device which is neither designed nor redesigned for use as a weapon; any device, although originally designed for use as a weapon, which is redesigned for use as a signaling, pyrotechnic, line throwing, safety, or similar device; surplus ordnance sold, loaned, or given by the Secretary of the Army pursuant to the provisions of section 4684(2), 4685, or 4686 of title 10; or any other device which the Attorney General finds is not likely to be used as a weapon, is an antique, or is a rifle which the owner intends to use solely for sporting, recreational or cultural purposes.
- 18 USC 921(23) - The term "machinegun" has the meaning given such term in section 5845(b) of the National Firearms Act (26 U.S.C. 5845(b)).
- 18 USC 922(o)(1) - Except as provided in paragraph (2), it shall be unlawful for any person to transfer or possess a machinegun.
- 26 USC 5845(a) - The term “firearm” means (1) a shotgun having a barrel or barrels of less than 18 inches in length; (2) a weapon made from a shotgun if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 18 inches in length; (3) a rifle having a barrel or barrels of less than 16 inches in length; (4) a weapon made from a rifle if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 16 inches in length; (5) any other weapon, as defined in subsection (e); (6) a machinegun; (7) any silencer (as defined in section 921 of title 18, United States Code); and (8) a destructive device. The term “firearm” shall not include an antique firearm or any device (other than a machinegun or destructive device) which, although designed as a weapon, the Secretary finds by reason of the date of its manufacture, value, design, and other characteristics is primarily a collector’s item and is not likely to be used as a weapon.
- 26 USC 5845(b) - The term “machinegun” means any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger. The term shall also include the frame or receiver of any such weapon, any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machinegun, and any combination of parts from which a machinegun can be assembled if such parts are in the possession or under the control of a person.
- 26 USC 5845(i) - The term “make”, and the various derivatives of such word, shall include manufacturing (other than by one qualified to engage in such business under this chapter), putting together, altering, any combination of these, or otherwise producing a firearm. (See 26 USC 5845(a) for the definition of "firearm" applicable to this section of code.)
- 26 USC 5861(c)-(f) - It shall be unlawful for any person ... (c) to receive or possess a firearm made in violation of the provisions of this chapter; or (d) to receive or possess a firearm which is not registered to him in the National Firearms Registration and Transfer Record; or (e) to transfer a firearm in violation of the provisions of this chapter; or (f) to make a firearm in violation of the provisions of this chapter; or ... . (See 26 USC 5845(a) for the definition of "firearm" applicable to this section of code.)
What, then, is the legal definition of a machinegun?
- A weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger; or
- the frame or receiver of any such weapon; or
- any part "designed solely or exclusively ... for use in converting a weapon into a machinegun"; or
- a "combination of parts designed and intended, for use in converting a weapon into a machinegun"; or
- "any combination of parts from which a machinegun can be assembled", if one person has possession or control of all of the parts.
See 26 USC 5845(b) and U.S. v. Bradley, 892 F.2d 634 (7th Cir. 1990).
You can see from this legal definition that, statutorily, a machinegun can be something other than a weapon that will fire multiple rounds with a single actuation of the trigger.
How, then, does the ARFULLAUTO kit comply with the law? Or in other words, how does the kit fail to meet the statutory definition of a machinegun, and at what point would the making of a machinegun occur, using the materials supplied in the kit?
- The kit does not constitute a "firearm" for the purposes of the GCA, because it is not an explosive, and it is not a weapon.
- Obviously, the kit does not comport with Definitions 1 or 2 of a machinegun. It is not a weapon at all, nor is it the frame or receiver of any such weapon.
- Definitions 3-5, however, have to do with parts that can be used to convert or assemble a machinegun. By definition, any part, or combination of parts, that can cause a semi-auto weapon to fire more than one round with a single actuation of the trigger are considered to be a machinegun, in and of themselves.
A fully-functional and complete BCGCW does not fit this criteria, but rather simply provides the same functionality as a Full-Auto bolt carrier, which, contrary to its name, does not cause a firearm to operate in Full-Auto.
The issue lies with a fully-functional and complete TCGTR. Because you can buy a stock AR-15, off the shelf, with a Full-Auto bolt carrier, and the simple addition of a fully-functional and complete TCGTR can make that AR-15 fire more than one round with a single actuation of the trigger, a fully-functional and complete TCGTR is, by definition, a machinegun, in and of itself, regardless of whether it needs any adjustment to make the operation of Full-Auto continuously successful, or not. The addition of a BCGCW is immaterial (doesn't add or subtract from the fact), when a fully-functional and complete TCGTR is present.
The fact, then, that the kit provides the materials from which a fully-functional and complete TCGTR can be made seems immaterial, but it is not. The materials provided in the kit are, in and of themselves, "parts". They can be used for a number of different things. A fully-functional and complete TCGTR is a "part", separate and distinct from the "part" or "parts" used to make it. The kit materials cannot, in and of themselves, or by themselves, be used to convert or assemble a machinegun, regardless of what other parts you have on-hand. Only a fully-functional and complete TCGTR fits the statutory language.
The difference is clear when put in proper context. If you were to go to your local hardware store, you would find a number of different washers, of varying size, thickness, inner and outer diameter. Each is considered a separate and distinct part, for none is completely interchangeable with another of different characteristics. By the same token, you would find, in that same store, varying pieces of flat metal, from which could be made, by simple modification of the metal material, door hinges, ladders, gutters, joist hangers, etc, each being a separate and distinct part from all the others, as well as from the material used to make it. A part is defined by its unique characteristics.
By the same token, the materials provided in the kit are separate and distinct "parts" from those "parts" that can be made from the materials, by modification to the materials themselves, and again, no part provided in the kit can or will make any firearm operate in Full-Auto. Only modification of the material provided in the kit to create a new "part" could and would make that possible.
However, once the materials in the kit are bent into the proper and/or correct shape, forming a fully-functional and complete TCGTR, they are, by definition, a machinegun, because they are a part or combination of parts that will cause a readily available firearm to operate in Full-Auto, regardless of whether it does so every time (continuously successful), or not. The necessity of fine-tuning that final part to comport to the unique characteristics of a particular firearm (to make it operate successfully in Full-Auto each and every time) are immaterial. (Incidentally, a 1/4-scale TCGTR would not comport with the legal definition of a machinegun, because it could not be used to convert or assemble any firearm into a machinegun.)
Is the kit "on thin ice", so to speak?
No. The law states what is or is not acceptable (legal or illegal), and you can only be held accountable for doing that which is specifically proscribed (forbidden), or not doing that which is specifically prescribed (mandated).
Put in proper context, if the law states that driving a vehicle at a rate of speed greater than that which is posted is forbidden (illegal), and the posted speed limit is 55mph, then going 55mph is, by very definition, legal. You are not required to be any particular distance away from the proscribed conduct. Once you cross that line into the "forbidden" zone, then you can be held to answer to the law, but not before. Anything up to that point, whether travelling at a rate of 25mph or 55mph is legal.
By the same token, once you manufacture a fully-functional and complete TCGTR from the materials in the kit, you may be held to answer to the law, but the materials from which you may do so are, themselves, completely legal to buy, sell, possess, transfer, etc.
What about the information on how to modify the kit? Isn't that illegal?
No, thoughts and information are not illegal to possess or transfer. It is the action taken to create a fully-functional and complete TCGTR that may overstep the bounds of the law, not the information on how to do so.
Please note that we will not "aid and abet" the manufacture of a machinegun, by advising you to create a fully-functional and complete TCGTR. We may give you all of the materials and information necessary to do so, but what you do with those materials and that information is up to you. We recommend simply using both for your education, in compliance with the purpose of the kit. That said, we will answer any and all questions about the kit or its modification that are hypothetical or general in nature, meaning that they are not specific to what "you" should do with "your" kit. The kit instructions are very specific on what one would need to do to modify the kit materials, if they wanted to, and include function checks and troubleshooting information one could use, if they so desired, though all of this is provided only for your education, in compliance with the purpose of the kit.
The ARFULLAUTO Kit is not likely to be compatible with Rock River Arms AR-15s (different depth inside the Lower), Colt M-4s (channel between hammer and rear take-down pin has a divider - the channel is not clear), and other similar AR-15s.

If you send a method of payment that does not meet the strict requirements specified on the Order Form, we will return your method of payment without processing your order.
This is the way we have chosen to do business at this time.
*See other sections of the FAQ for more information.
After providing your shipping information, creating a PIN, and specifying the number of kits you want to order, your order will be entered into the system with a status of "Order Received", and you will receive an Order Number (which you will enter into the Memo: field of a Money Order) and instructions on how to pay with a Money Order. You will need to retain a record of your Order Number and PIN, as this is the only way we provide status of your order, throughout the process, as well as access to kit instructions and information, once your kit has shipped.
When we receive payment for your order, we will upgrade the status of your order to "Payment Received" or "Payment Returned".
When we process and ship your order, we will upgrade the status of your order to "Order Shipped", and your shipping and other identifying information will be deleted from our system.
We do not keep any information about your order, other than the Order Number, PIN, Quantity of kits ordered, and Zip.
To access your order status at any time, simply click on the "Order Status and Kit Instructions" link at the top of this page, and enter your Order Number and PIN. You will also use this method to receive your kit instructions.
If you have any questions that are not covered by your order status or the FAQ at the link at the top of this page, you may contact us using the information on the Contact Us link at the top of this page. Once your payment is received, you may contact us directly, using the Contact Form on the Order Status page.
How is your privacy assured?
- It starts with the very first contact you make with us. Any and all Internet traffic that carries your information to our site occurs ONLY over a secured connection. The ordering process, the status updates, and messages, all occur ONLY through encrypted and secured connections. From start to finish, your communication with us is all secured.
- Your personal information is shared with us only over a secured Internet connection. No identifying information is transmitted to us through the mail, where prying eyes might be watching; only an Order Number is sent with the Money Order. You don't even need to put your Return Address on the envelope, if you don't want to; you can put ours, if you prefer. In fact, if you want to leave your name blank (or simply put Resident) in the ordering process, we're fine with that, though you will probably want your name on the package if you aren't the only individual who might receive mail at the designated shipping address.
- We require that you leave the From: field of the money order blank, so that no one, except you, can trace your payment to us. This protects both you and us in many ways. The receipt portion of the money order that you keep is your proof that you have paid, and that we have received your payment, because no one can cash it except the entity listed in the To: field of the Money Order. This receipt portion also makes it possible for you to receive a replacement, should your money order become lost, stolen, or damaged. (Because no other information is sent through the mail, you retain plausible deniability that you even sent a Money Order, let alone what it was for.)
- No information-laden emails are saved on some computer, because there are none. The moment we mark your payment as received, you are able to communicate with us through a secured contact form. The only emails that will ever travel between you and us are those that we send saying that there is a status update to your order, and this only occurs if you want to provide us with an email address, (not required) which you can request that we delete from the system any time after we have received payment for your order. This is simply a notification to you that you should log back into the website to review updates to your order, at your leisure.
- Your identifying information (your name and address) are encrypted on our system from the moment we receive them. Even an ABC entity who had access to the file system on our server wouldn't have access to your identifying information because of the double-key encryption we use to protect your information.
- The moment your order is marked as shipped, your identifying information (your name and address) are removed from our system. You still have the ability to communicate with us through the secured contact form on the order status page. No identifying information can be forced from us about anything we send you, because once we send you anything, all identifying information is deleted.
- Your kit is shipped in an unmarked package, with your address as the Return Address, and no identifying information is contained in the package, so even prying eyes won't know who it is from, nor will they know what it is for, since the instructions are not shipped, but rather are viewable online only, once your package has shipped. (Because no product information is sent through the mail, you retain plausible deniability as to what, if anything, was even received from us.)
- We do not communicate through phone calls or emails. Prior to us receiving payment for your order, all communication occurs via snail mail, which we destroy once we reply to you. All communication that occurs thereafter can be handled through our secure messaging system on the site. No digital communications occur over unsecured lines.
- We do not retain any information other than your Order Number, PIN, Quantity of kits ordered, and Zip. If your shipment is returned to us for an incorrect address, we will update the status of your order to "Incorrect Address" and wait for you to contact us with updated information. (If your package is shipped, we no longer have the ability to contact you, unless and until you contact us, which means we can't give your information to anyone, and no one can force it from us. You even have the ability to request that we delete any email address we have on file, assuming you even provided one.)
Why do we do this? Why not allow phone calls, emails, checks, credit cards, and other trackable information, like every other website does?
- We believe in your right to privacy and anonymity in any transaction between private parties. We believe we have the same right.
- We believe that no governmental agency, or other entity, has a right to your information, so long as you aren't hurting anyone or doing anything illegal. The sale of this kit is a completely legal and lawful transaction between private parties.
- We believe that the world would be a better, and much more simple, place, if private transactions were not needlessly scrutinized by alphabet soup agencies, and we aim to set a standard (including communication, ordering process, payment, retention of information, etc) that others can follow in their private transactions, if they so choose.
The instructions become available on that page as soon as your order is marked as shipped.
