Legal Notice and Terms of Use

Effective date: 27 September 2026. This notice applies to the Pew-Takedown website, the Pew-Takedown repository and everything in it, the data files and machine-readable exports built from it, the printable work-order sheets, and any application, website or service that incorporates any of them (together, the "Materials"). The Materials are published by Fundamental Build LLC ("we", "us"). By reading, downloading, copying or otherwise using any of the Materials you agree to this notice. If you do not agree, do not use the Materials.

The plain-language safety summary is in docs/DISCLAIMER.md. The licence under which the content and tooling are made available is in LICENSE. This notice is in addition to both. Where this notice and the LICENSE differ about the terms of the licence itself, the LICENSE controls.

1. The Materials are general information, not advice

The Materials are provided for general informational and educational purposes only. They do not constitute, and must not be relied on as, gunsmithing, engineering, technical, safety, professional or legal advice, and no professional relationship of any kind is created by your use of them. Nothing in the Materials is a recommendation that you perform, or are qualified to perform, any procedure they describe.

2. The Materials are third-party information compiled from sources of varying reliability

The Materials are compiled from third-party sources: manufacturers' owner's manuals, government and military technical manuals, published references, parts distributors' listings, articles, videos, forum posts and community knowledge. Some of those sources are authoritative; some are not; and some of the information may be incomplete, out of date, misattributed or simply wrong.

We record where each item of information came from and give each entry an editorial confidence rating. A source citation or a confidence rating is our opinion about the evidence. It is not a certification, a verification, or a guarantee of accuracy. A procedure, parts list, torque value or statement attributed to a manufacturer is our transcription or summary of a document that manufacturer published; the manufacturer's own current document for your specific firearm controls, and where they differ, the Materials are wrong. Values shown as "reported" by anyone other than a manufacturer are exactly that: what that person or publication said, reproduced so you can judge it. They are not specifications.

Firearm designs change during production without a change of model name. Two firearms with the same markings may differ in construction, parts and procedure. The Materials cannot account for the specific firearm in front of you.

3. No affiliation; trademarks

Fundamental Build LLC and the Pew-Takedown project are not affiliated with, endorsed by, sponsored by or approved by any firearm manufacturer, importer, distributor, parts maker, publisher or government body named in the Materials. Manufacturer names, model names, logos and part numbers are the trademarks or property of their respective owners and are used only to identify the firearms and documents to which the Materials refer. Manufacturers' documents are linked, not reproduced, except for short quotations used to identify the source of a specific statement.

4. Work on a firearm belongs with a licensed and insured gunsmith

Any work on a firearm beyond the routine field stripping and cleaning described in that firearm's own owner's manual — including detail disassembly, removal of a barreled action from a stock or chassis, reassembly, the application of any torque value, refinishing or coating, and any work touching a fire-control component, a safety mechanism, headspace or the barrel — should be performed only by a licensed, insured and appropriately qualified gunsmith. Nothing in the Materials qualifies any person to perform such work, and the Materials are not a substitute for professional training, the manufacturer's service documentation or the judgment of a qualified professional who has the firearm in hand. If you are not such a professional, the Materials are provided so that you can understand a design and know what to expect — not so that you can do the work yourself.

5. Assumption of risk

Firearms are inherently dangerous. You acknowledge that disassembling, reassembling, adjusting, torquing, refinishing or otherwise working on a firearm — whether or not in accordance with the Materials — can result in death, serious personal injury, property damage, an unsafe or malfunctioning firearm, the loss of a manufacturer's warranty, and liability to third parties, and that an incorrectly reassembled firearm may be unsafe in ways that are not visible. You voluntarily assume all such risks. Any reliance you place on the Materials is strictly at your own risk, and any decision to act on them is yours alone.

6. No warranties

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE MATERIALS ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY WARRANTY OF ACCURACY, COMPLETENESS, CURRENCY, RELIABILITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, OR THAT THE MATERIALS ARE SUITABLE FOR OR APPLICABLE TO ANY PARTICULAR FIREARM. WE DO NOT WARRANT THAT ANY PROCEDURE IS SAFE OR CORRECT, THAT ANY PARTS LIST OR TORQUE VALUE IS ACCURATE OR APPLIES TO YOUR FIREARM, THAT ANY LINKED DOCUMENT IS CURRENT OR WILL REMAIN AVAILABLE, OR THAT ERRORS WILL BE CORRECTED.

7. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL FUNDAMENTAL BUILD LLC, ITS MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, AGENTS, CONTRACTORS, LICENSORS, CONTRIBUTORS OR MAINTAINERS, OR ANY PERSON OR ENTITY THAT DISTRIBUTES OR INCORPORATES THE MATERIALS (TOGETHER, THE "RELEASED PARTIES") BE LIABLE FOR ANY DEATH, PERSONAL INJURY, PROPERTY DAMAGE, OR DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES OF ANY KIND — INCLUDING WITHOUT LIMITATION DAMAGE TO OR LOSS OF A FIREARM, COST OF REPAIR OR REPLACEMENT, LOSS OF WARRANTY, LOSS OF USE, LOST PROFITS OR LOSS OF BUSINESS — ARISING OUT OF OR IN ANY WAY CONNECTED WITH THE MATERIALS OR YOUR USE OF OR RELIANCE ON THEM, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, WARRANTY OR ANY OTHER LEGAL THEORY, AND EVEN IF A RELEASED PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IF, NOTWITHSTANDING THE FOREGOING, A RELEASED PARTY IS FOUND LIABLE, ITS TOTAL AGGREGATE LIABILITY WILL NOT EXCEED THE AMOUNT YOU PAID FOR ACCESS TO THE MATERIALS, WHICH IS NOTHING.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for certain kinds of damage. In those jurisdictions the exclusions and limitations above apply to the fullest extent the law allows, and our liability is limited to the greatest extent permitted.

8. Indemnification

You agree to indemnify, defend and hold harmless the Released Parties from and against any and all claims, demands, losses, liabilities, damages, judgments, costs and expenses (including reasonable legal fees) arising out of or relating to your use of the Materials, any work you perform or cause to be performed on a firearm in reliance on them, your violation of this notice, or your violation of any law or of the rights of any third party.

9. You are responsible for compliance with the law

Firearms are regulated, and the law differs between countries, states, provinces, counties and cities and changes over time. Some configurations, modifications, parts and procedures that are lawful in one place are restricted or prohibited in another. You are solely responsible for knowing and complying with every law that applies to you, including laws on the possession, modification, transport and transfer of firearms and firearm parts. Nothing in the Materials is legal advice, and a legalNotes field in an entry is a general caution, not a legal opinion. The Materials document how firearms come apart for cleaning and maintenance, which is the ground a manufacturer's owner's manual covers; they do not document, and we decline contributions that document, converting a firearm to fire automatically, defeating a safety mechanism, manufacturing a regulated component or circumventing any legal restriction.

10. Third-party documents and links

The Materials cite and link to documents and websites that we do not control, including manufacturers' manuals hosted by the manufacturer or by third parties. We are not responsible for their content, accuracy or availability; a link is not an endorsement; linked documents may be revised, moved or withdrawn without notice; and your use of them is subject to their owners' terms. A record that a link "resolved" on a given date means only that a document was retrievable at that address on that date.

11. Applications that incorporate the Materials

Any application, website, service or document that incorporates or displays any part of the Materials (a "Downstream Application"), including Fundamental Build LLC's own products, must present this notice (or a substantially equivalent one) and the plain-language disclaimer to its users together with the information; must display each entry's confidence rating and, where recorded, the manufacturer's stated position on owner disassembly; must display every torque value with its source and must never present a value reported by a non-manufacturer source as a manufacturer specification; and must not represent the Materials as verified, certified, authoritative or as the manufacturer's own. The operator of a Downstream Application is solely responsible for its own users, its own compliance with the law, and any professional services it offers or performs.

12. Errors, corrections and changes

We make reasonable efforts to record sources accurately, but we do not undertake to verify, update or correct the Materials, and we may add to, change or remove any part of them at any time without notice. We may revise this notice at any time; a revised notice takes effect when it is published in the repository, and your continued use of the Materials after that is acceptance of it. If you believe something in the Materials is wrong, please report it through the repository's issue tracker; a report does not create any obligation on our part.

13. Intellectual property and licence

The database content is licensed under the Creative Commons Attribution-ShareAlike 4.0 International licence and the tooling under the MIT licence, each as set out in LICENSE. Those licences grant rights in what we have created; they grant no rights in any manufacturer's document, trademark, image or other material referred to in the Materials, all of which remain the property of their owners.

14. General

If any provision of this notice is held unenforceable, it will be enforced to the maximum extent permissible and the remaining provisions will remain in full force. Our failure to enforce any provision is not a waiver of it. Headings are for convenience only. This notice, together with the LICENSE and the plain-language disclaimer, is the entire statement of the terms on which the Materials are made available.
