California AB 1263 Explained: Ordering Firearm Parts in 2026 | Moriarti

California continues to set the pace for firearm regulation—and AB 1263 is one of the most impactful changes yet for gun owners who buy parts online. If you’re a California resident who builds, upgrades, or maintains firearms using aftermarket components, this law will directly affect how you order parts starting January 1, 2026.

At Moriarti Armaments, we believe informed customers are protected customers. This guide breaks down what AB 1263 actually requires, which parts are affected, how it changes online ordering, and why buying direct from a compliant manufacturer matters more than ever.

California Assembly Bill 1263 introduces mandatory age and address verification for firearm parts shipped into the state. Unlike previous laws that focused on serialized components, AB 1263 applies broadly to any tools, parts, or part sets:

“Clearly designed and intended for use in manufacturing firearms.”

That language matters—and it’s why this law reaches far beyond receivers or frames.

Beginning January 1, 2026, retailers must verify both the identity and eligibility of California customers before shipping qualifying parts.

For years, California shooters have relied on online retailers to source:

• Replacement parts

• Performance upgrades

• Competition components

• Maintenance items

AB 1263 fundamentally changes that experience. The days of anonymous checkout and standard shipping are over for California buyers.

If a retailer cannot meet the law’s verification requirements, they cannot legally ship qualifying firearm parts into California—period.

Because the law uses intentionally broad language, many common aftermarket components are expected to fall under AB 1263. These likely include:

• Triggers and trigger components

• Trigger reset systems

• Grip modules and frames

• Slides and barrels

• Fire control components

• Recoil systems and spring kits

• Pins, screws, and internal hardware

In short: if it’s designed specifically for a firearm, expect verification requirements.

For affected parts shipped to California, AB 1263 requires four distinct compliance steps:

1. Legal Acknowledgment

Customers must affirm they understand California law before completing checkout. This includes acknowledgment of AB 1263 and its restrictions.

2. Age Verification

Buyers must prove they are 18 years or older using a valid, state-issued ID such as a driver’s license.

3. Address Matching

Orders must ship only to the address listed on the provided ID. No alternate shipping addresses, no exceptions.

4. Adult Signature at Delivery

Shipments must use Adult Signature Required services through USPS, FedEx, or UPS.

This ensures firearm parts are delivered directly into verified hands—not left unattended or redirected.

Here’s where things get complicated.

AB 1263 allows purchases at 18+, but most carriers define “adult signature” as 21+. That means:

• Customers aged 18–20 may legally purchase parts

• But may be unable to receive them without a 21+ signer present

This is a real-world issue, not a theory—and it’s something Moriarti is actively planning around with carrier solutions and customer guidance.

Compliance is not optional—and it’s not simple.

Retailers must now implement systems to:

• Verify age before fulfillment

• Match shipping addresses to IDs

• Securely handle sensitive personal data

• Comply with California Consumer Privacy Act (CCPA)

• Maintain audit trails in case of enforcement review

Many smaller sellers simply will not invest in this infrastructure.

That’s why California buyers will see fewer shipping options—and more “cannot ship to CA” notices—moving into 2026.

After January 1, 2026, expect:

• Fewer sellers shipping to CA

• Longer checkout processes

• Required ID uploads

• Signature-required delivery delays

• Higher prices as sellers pass on compliance costs

Most importantly, expect a shift toward direct-to-consumer manufacturers who can legally support California customers.
