"The TDP"
When most people mention “TDP”, they are talking about the Colt M16A1 Technical Data Package. This is the O.G. that still defines most of the requirements for today’s AR-style military hardware.
We assume that you have read the preceding articles, so you are familiar with the principles, conventions, and symbology. If not, please go back to Spec to Inspect.
We have a very large collection of both M16A2 and M4 TDP drawings.  Below, you will find some of the key TDP drawings that we have collected.  We have hundreds of additional drawings and will be adding more of these as we are able.
If you are looking for something and don’t see it, submit a request below. If we have it, we will convert it from its original TIFF format and add it to the collection. Note that we don’t have many M16A1-specific drawings (we get a lot of requests for these).
We have been able to locate some newer versions of the drawings, which are the ones with isometric views. If you are interested in the originals of these, contact us and we can send you a link.
If you find drawings that we don’t have, please submit them and we will get them posted for all to enjoy.
Disclaimer
The drawings provided below are provided for your entertainment and academic purposes. These drawings have been collected from all over the internet. As such, we were not the ones to release them to the general public.
However, if we are asked (by Colt, DoD, etc.) to remove any or all these drawings, we will do so. We sincerely hope that this will not happen, and we don’t see a very good reason if it does. Our government has sold, given, and abandoned some version of these arms in just about every country in the world. If anyone, anywhere wanted to manufacture the M16, they have already reverse engineered it; they would not need 50+ year old technical drawings.
For now, we hope these drawings contribute to your enjoyment of this incredible weapon system. If you find something useful, we recommend that you download it, as it may not always be available.

Request a TDP Drawing
As mentioned, we have a very large collection of TDP drawings. We will be continuously adding more to our published library as free time permits. If you are looking for something in particular, and don’t see it, let us know. If we have it, we will convert it and publish it.
Please include the weapon system (e.g. M16, M4) and the component or assembly name. If you have the TDP drawing number, that can help too.
Please provide your email in case we need to follow up with your request (for clarification of the request, to let you know we don’t have what you are looking for, or to let you know that we’ve added the requested drawings to the library). We will only ever use this email address in correspondence related to this request. If you don’t provide your email address and you don’t see your requested drawings added to the library, you can assume that we either didn’t understand your request or we don’t have the drawings you are looking for.
