80 Lower publishes detailed guides on configuring California-legal AR-15s under SB 23 '99 Assault Weapons Laws. Their content covers:

Two legal paths for CA builds: Fixed-magazine ARs (best for range/accuracy) use AR MagLock and KingPin rear takedown pins to prevent standard magazine removal without disassembly. Featureless ARs (better for self-defense scenarios) require fin grips or featureless grips, fixed A2-style stocks, angled foregrips like the Magpul AFG-2, and recoil-reducing muzzle devices like Spike's Tactical R2 brakes.

California-compliant parts they carry: - Fin grips and featureless grips (replaces standard pistol grips) - Fixed A2-style stocks - Angled foregrips (vertical grips are banned) - Muzzle brakes and compensators (flash suppressors are banned) - AR MagLock systems - KingPin rear takedown pins

They explicitly note that 10-round magazine capacity limits apply and high-capacity magazine bans have been upheld by California courts.
