Site terms & privacy

Reference information; no fit guarantee

Firearm Lab publishes compatibility claims, source references, and reported experiences. Records can be incomplete, incorrect, or out of date. A listing, badge, vote, response, setup, or retailer link is not a promise that a product will fit your particular firearm or work with other installed parts.

Model names alone are not enough to establish compatibility. Generations, variants, production changes, tolerances, previous modifications, adapters, and included hardware can change the result. Check the exact products and current manufacturer requirements before buying. Have the specific setup evaluated by the manufacturer or a qualified armorer before use. Do not force an installation or modify a product based on a site listing.

The site does not provide individualized gunsmithing, engineering, or safety advice. Mounting or clearance evidence does not establish safe function, reliability, legality, or suitability for defensive or duty use. Follow manufacturer instructions and applicable law.

What evidence labels establish

Evidence labels identify the recorded basis for a claim. Manufacturer documented means a claim is attributed to the cited manufacturer source; it is not an independent Firearm Lab test. Interface match is an inference from recorded interface information, not confirmation of that exact pairing. Dates identify the recorded evidence or calculation date and do not promise continuing accuracy.

Lab tested describes the recorded observation for the identified configuration and scope. It is not a certification, standardized safety approval, or assurance about every unit, production revision, or combination of parts. Review the source, scope, limitations, and date rather than relying on a badge alone.

Community contributions describe their authors’ experiences or claims. Moderation is not independent verification. Company and manufacturer badges identify an affiliation checked by staff, not a warranty, endorsement, or certification of the author’s claims.

Information provided as is

TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE SITE AND ITS INFORMATION ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ACCURACY, COMPLETENESS, CURRENTNESS, AVAILABILITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT GUARANTEE THAT A LISTED PRODUCT WILL FIT OR THAT USING SITE INFORMATION WILL PRODUCE A PARTICULAR RESULT.

This provision concerns the site and its information. It does not change a seller’s or manufacturer’s obligations, a product warranty, or any right that applicable law does not allow to be excluded.

Limits on liability; rights preserved

To the extent permitted by applicable law, the site operator will not be liable for indirect, incidental, special, consequential, or punitive damages arising from use of, or inability to use, the site or reliance on its information, including related loss of profits or business opportunities.

Nothing in these terms excludes or limits liability or remedies that cannot lawfully be excluded or limited, including liability for fraud or intentional misconduct. These terms do not require you to waive non-waivable consumer rights. Any limitation applies only to the extent it is lawful and enforceable in the circumstances.

Retailers, purchases, and commissions

A retailer link sends you to a third-party business. Purchases made there are with that seller, under that seller’s product descriptions, checkout terms, warranties, and return policy. Firearm Lab does not handle those transactions or promise a refund for a third-party purchase. Confirm compatibility and the seller’s return policy before ordering. This does not remove any rights or remedies you may have under applicable law.

We may earn a commission when you buy through retailer links. Paid relationships do not determine compatibility answers or evidence strength. Any sponsored placement must be labelled and separate from evidence ordering. Third-party prices, stock, specifications, and linked content can change.

Accounts and contributed content

Use an accurate identity and do not impersonate another person or business. Follow the community guidelines. Submit only content you have the right to share, and disclose relevant business relationships or compensation. Do not publish private information or confidential support correspondence without permission.

You retain ownership of your contributed content. When you submit content for publication, you grant the site operator a non-exclusive, worldwide, royalty-free license to host, reproduce, display, format, and distribute it as needed to operate the site and its backups. This does not transfer ownership or authorize an unrelated endorsement using your identity. Contact us to request correction or removal; requests are reviewed manually, and backup copies or records required by law may remain.

Staff may review, withhold, or remove contributions and restrict abusive accounts. Publication does not mean staff independently tested or adopted every contributed statement. Report an error with the page URL, exact products, and any supporting evidence. We do not promise a response time, continuous monitoring, or automatic notifications.

Account agreement and changes

When creating a member account, you must expressly agree to the linked version of these terms. The acceptance record identifies that version and the server-recorded time. Existing accounts are not treated as having accepted a new version simply because this page changed.

Changes will be published with an updated version date. A new version does not retroactively alter the version previously accepted. No provision of these terms requires arbitration or waives a jury trial or class action. If a provision is unenforceable, the remaining provisions apply to the extent allowed by law.
