One of the most complex aspects of selling firearms online is navigating the patchwork of state laws. When you ship a firearm, you must comply with the laws of your customer's state—not just your own. This guide covers key considerations for interstate firearms shipping.
The Golden Rule
When selling firearms online, remember: you must comply with the laws of the destination state. Even if a firearm is perfectly legal in your state, it may be prohibited or restricted where your customer lives.
Key Compliance Areas
Age Requirements
Age requirements vary by state and firearm type:
- Federal minimum: 18 for long guns, 21 for handguns
- Some states require 21 for all firearms (California, Florida, Hawaii, Illinois, Vermont, Washington)
- Semi-automatic restrictions: Some states have higher age requirements for semi-automatic rifles
Prohibited Firearms
Certain firearms are prohibited in specific states:
| State | Key Restrictions |
|---|---|
| California | Assault weapons roster, handgun roster, magazine limits |
| New York | SAFE Act restrictions, assault weapon definitions |
| New Jersey | Assault weapon ban, magazine limits |
| Massachusetts | Approved firearms roster, assault weapon ban |
| Connecticut | Assault weapon restrictions, registration requirements |
| Maryland | Handgun roster, assault weapon restrictions |

Magazine Capacity Limits
Many states restrict magazine capacity:
- 10 rounds: California, Connecticut, Maryland, Massachusetts, New Jersey, New York
- 15 rounds: Colorado, Vermont
- No limit: Most other states
Permit Requirements
Some states require permits before purchase:
- Illinois: FOID card required
- Massachusetts: LTC or FID required
- New Jersey: FID and permit to purchase

Best Practices for Compliance
1. Verify State Laws Before Shipping
Before accepting any order, verify:
- The firearm is legal in the destination state
- The customer meets age requirements
- Any required permits are in place
- Magazine capacity is compliant
2. Use Compliant FFLs
Partner with receiving FFLs who:
- Understand their state's requirements
- Will properly complete the transfer
- Are licensed and in good standing
3. Document Everything
Maintain records of:
- Customer's state of residence
- Receiving FFL information
- Verification steps taken
- Any permits or documentation provided
4. Configure Product Restrictions
Set up your e-commerce platform to:
- Block prohibited items from restricted states
- Enforce age requirements at checkout
- Display state-specific warnings
- Require permit information when needed
