This list is absolutely, by no means, an authoritative list of all FFLs willing to transfer off-list rifles in California. FFLs will only be listed here if it is with their express consent, and to that end, I am personally and exclusively maintaining this list; any added via other editors will be backed out unless I can confirm that the dealer consents to the listing. This is because some dealers have stopped transferring off-list lowers after being publicly "outed", and quiet transfer dealers tend to eventually become bolder unless they get scared off in the meantime.
Known non-transferring dealers are not as protected; other editors may add to that list. However, if I get a store contacting me to say they actually ARE transferring, I'll be happy to reverse that. This is mostly a guide to which stores not to harrass about performing transfers.
