Gun-rights advocacy group in the United States
The USPS is moving to allow concealable firearms to be mailed domestically under safeguards similar to rifles and shotguns. Democratic attorneys general in about two dozen states are opposing the plan, arguing it undermines state gun laws and enables access for people not legally permitted to possess firearms.
New York and California are pushing legislation to require firearm-blocking technology in 3D-printers to detect gun designs before printing. Critics warn it might not work and could raise privacy and rights concerns. The effort builds on a surge in privately made guns; a study group will assess feasibility before any mandate takes effect.
