Love reading the thread trees and learning , Building a Retro AR10A2 in Far Nor Cal (Ultra Rural Eastern Shasta County)

I have a Stripped Armalite AR10A2 (carry handle) upper (Early Non FA model) and ordered a Matrix Arms Armalite pattern Lower . I plan on recreating an early 1990s era Armalite AR10A2 retro classic style rifle in either 20" HBAR or 18.5 " barrel configuration with A2 style FS/GB. I know I will want Armalite pattern everything including Armalite AR10A LPK and Barrel Nut and Armalite pattern Barrel & BCG. Seeing how I live in California where Armalite AR 10 lowers are banned by name I noticed that Armalite sells California legal Rifles. What Lowers do they incorporate in their California legal Rifles and how are they rollmarked or what markings are utilized to allow sale in California ? I ordered the Matrix lower already but would love to mate my rare upper with an actual Armalite Lower (California Legal one) . But anyhoo that digression aside I want to use Green Armalite A2 stock,PG and Green A2 Rifle handguards to maintain the A2 look & configuration . Could any posters here chime in with Parts advice (Mags) (Barrel Sources and BCG advice ) and any helpful hints are greatly appreciated ...

For a Matrix Arms Armalite pattern lower mated to an "Original" Armalite AR10A2 stripped upper that I'm building a Rifle around which Magazines should I look for that will work ???
