Community guidelines

Share useful details

Tell us what you tried, what worked, and what didn’t. Include the exact firearm model, generation, and part, plus any adapters, changes, or problems.

• Be clear about what you tried yourself and what you heard from someone else. If you’re unsure, say so.
• Include a link when you refer to manufacturer information or another source. A vote alone does not prove that a part fits.
• Disagree respectfully. No personal attacks, pretending to be someone else, spam, organizing votes to manipulate results, or sharing someone’s private information.
• Say if you work for a company, received a free or discounted product, or were paid in connection with what you’re sharing.
• Only share photos you own or have permission to use. Leave out serial numbers, addresses, account details, and private messages. Get permission before sharing a conversation with customer support.

We review contributions before publishing

The team reviews new comments, questions, replies, and setups before they appear publicly. Honest reports of problems are welcome, just like positive experiences.

We may ask for more information, leave a submission unpublished, remove content, or restrict accounts that break these rules. Publishing a contribution does not mean Firearm Lab tested the products or confirmed the claim.

Found a mistake? Tell us.

Use the correction link on a model or part page, or send a correction here. Include the page link, what needs changing, the exact products, and a public source if you have one.

We check the information before changing an answer. While we investigate, we may mark it as under review. An unconfirmed combination is different from one known not to fit. Votes alone do not change compatibility answers.

Approved corrections appear in the compatibility record’s change history, with an explanation and contributor credit when available.

Disagree with a review decision? Ask us to take another look. Include your username, a link or submission reference, and any new details. Reviews are handled by the team, so we can’t promise a response time or an automatic update.

Speaking for a manufacturer

Start with a company account using your company’s public name and website. Verifying your email does not verify your company or your role.

1. We contact the company through an official channel to check who you are and whether you can speak for it.
2. We keep the details of that check private and link your account to the manufacturer you represent.
3. To post with a manufacturer response badge, reply about that manufacturer’s part and include a secure link to a public source. The team reviews the reply before publishing.

The badge shows that we checked your connection to the manufacturer. It does not mean we tested the product or confirmed everything in the reply. It does not give you control over member comments or criticism.

A verified shop or distributor cannot use a manufacturer response badge for a brand it does not represent. If your role changes, tell us. Earlier replies keep their original attribution, but the current badge is removed when your verified role ends.

Retailer links and paid placements

No one can pay for a different compatibility answer, a stronger evidence label, removal of an honest critical report, or special treatment in reviews. Manufacturer contributions follow the same evidence rules as everyone else’s.

We may earn a commission when you buy through retailer links. Any paid placement will be clearly labelled and kept separate from how compatibility evidence is ranked. We’ll explain paid features before introducing them. Commenting and voting will remain free.
