I just saw this update from CRPA -

Real ID Update: Part 3"Update Regarding Use of Non-REAL IDs for Firearm Purchases
NRA and CRPA attorneys recently received further clarification from the Bureau of Alcohol, Tobacco, Firearms and Explosives (“ATF”) regarding the use of non-REAL IDs when purchasing a firearm at a California license firearms dealer. According to ATF, California licensed firearm dealers:
[M]ay accept post-January 22, 2018 licenses/identification documents that meet the definition in 18 U.S.C. 1028(d) in fulfilling their requirements under 18 U.S.C. 922(t)(1)(C) and 27 CFR 478.124(c)(3)(i). However, licensees may consider asking for additional documentation (e.g., passport) so that the transfer is not further delayed.
As a result, California residents who are issued non-REAL IDs after January 22, 2018, by the California Department of Motor Vehicles (“DMV”) may use their IDs for the purposes of purchasing a firearm, even if the ID contains the language “FEDERAL LIMITS APPLY” on the front of the license and states on the back of the license that 'This card is not acceptable for official federal purposes.'
