California’s newly passed AB1263, often referred to as the “online parts ban,” officially takes effect on January 1, 2026—and it’s already creating ripple effects far beyond what most gun owners expected. While much of the early discussion focused on how the law will restrict online purchases of firearm parts and accessories, a newer and more concerning twist is emerging: California gun shops and FFLs may soon face major shortages due to distributor-level compliance requirements.

Starting in 2026, California residents ordering gun parts online must:

• Provide a matching ID and residential address
• Receive shipments only at the address on that ID
• Sign for every single delivery
• Acknowledge a state-mandated statement
• Comply with restrictions covering parts, accessories, 3D printers, and even digital files

Even if a company is still willing to ship to California, every transaction now involves additional hoops—and retailers must comply too.

Most California gun shops source their inventory online from major distributors. That means AB1263’s requirements now apply not just to consumers, but to FFLs bringing inventory into the state.

One major distributor, RSR, has already notified California shops that it will only ship to FFLs who complete and file a new compliance affidavit. This is their method of meeting AB1263’s “reasonable controls” requirement before the law kicks in.

Shops that don’t know about the affidavit—or don’t submit it in time—may soon find themselves cut off from inventory, leading to:

• Empty shelves
• Delayed restocking
• Increased prices
• Widespread confusion in early 2026

With lawsuits already being prepared, the industry expects legal challenges—but courts can take years, and the law will be enforced in the meantime.

AB1263 doesn’t just impact online shoppers. It threatens the entire supply chain for California firearm retailers. Add in exemptions for law enforcement and sweeping restrictions on parts, accessories, and even code, and the law is poised to create:

• A two-tier system of rights
• Major constitutional battles
• Possibly the worst inventory disruptions California gun stores have seen in years

If you buy parts in California—or work at an FFL—January 1, 2026, is shaping up to be chaotic. With distributors already tightening requirements, shortages and confusion are almost guaranteed. Staying informed and preparing early will be critical.
