California law in detail
- Heavily restricted (NFA) — SBRs, suppressors, and machine guns are prohibited for civilians. Only SBS may be obtainable with special permits in rare cases.
- Yes (Assault Weapon Ban) — Semi-auto rifles with features like pistol grips, thumbhole stocks, folding/telescoping stocks, or flash suppressors are banned. Fixed-magazine 'featureless' builds are common workarounds.
The federal rule
Suppressors are regulated under the National Firearms Act. The federal tax on a suppressor dropped from $200 to $0 on January 1, 2026, but you still need an approved ATF Form 4 and registration before taking possession. State law can ban them outright even when federal law allows them.
