How we work

  • Every page lists its sources

    Claims link to manufacturers, agencies and published references, so you can check them yourself.

  • Reviewed by a person

    AI can help research and draft, but a named editor checks and approves every page before it is published.

  • Official rules first

    Hunting and firearm regulations always link to the official agency, with the date we last verified them.

  • Education, not sales

    We do not sell firearms or ammunition and do not host listings or transfers.
