Can You Ship AR-15 Parts to Your Door?

Building an AR-15 at home offers flexibility and customization that many firearm enthusiasts appreciate. However, understanding what can be shipped directly to your door versus what requires an FFL transfer is essential for staying compliant with federal law. This guide breaks down exactly which AR-15 parts you can order online and receive at home, which components must be shipped to an FFL dealer, and the specific requirements that govern these regulations.

Understanding FFL Requirements for AR-15 Parts

The distinction between parts that can be shipped to your home and those requiring FFL transfers centers on one key component: the lower receiver. Under federal law, the lower receiver is legally considered the firearm itself, even though it’s just one part of the complete rifle. This classification means that while you can order most AR-15 components online and have them delivered to your doorstep, the lower receiver must follow the same regulations as purchasing any other firearm.

The ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) established this framework because the lower receiver contains the fire control group and serial number. It’s the only part of an AR-15 that requires serialization, making it the regulated component that tracks ownership and transfers.

Parts That Can Ship Directly to Your Home

The vast majority of AR-15 components can be shipped directly to your residential address without any FFL involvement. These include:

• Complete upper receivers: Despite containing the barrel and bolt carrier group, upper receivers are not considered firearms under federal law
• Barrels: All barrel lengths, including those under 16 inches for pistol builds
• Bolt carrier groups: Both standard and enhanced models
• Handguards and rail systems: Free-float, drop-in, and quad rail varieties
• Stocks and pistol braces: Adjustable, fixed, and stabilizing braces
• Triggers and fire control parts: Single-stage, two-stage, and drop-in trigger units
• Lower parts kits: Everything except the lower receiver itself
• Magazines: Subject to state and local law restrictions on capacity
• Optics and sights: Red dots, scopes, iron sights
• Muzzle devices: Flash hiders, compensators, and brakes

Parts Requiring FFL Transfer

Only a few AR-15 components require shipping to an FFL dealer:

• Complete lower receivers: Whether stripped or assembled
• 80% lower receivers: Once completed beyond 80%, these become firearms
• Registered drop-in auto sears: NFA items requiring additional ATF approval
• Complete firearms: Fully assembled AR-15 rifles or pistols

When is an FFL Needed?

An FFL transfer becomes necessary whenever you’re purchasing a serialized lower receiver or complete firearm. This requirement applies whether you’re buying from an online retailer, at a gun show, or through a private sale (in states that mandate background checks for private transfers). The process typically works as follows:

1. Select your lower receiver or complete firearm online
2. Choose an FFL dealer near you (most online retailers maintain FFL finder tools)
3. Complete your purchase with the FFL dealer’s information
4. The seller ships the item to your chosen FFL
5. Visit the FFL to complete ATF Form 4473 and background check
6. Pay the transfer fee (typically $20-75 depending on location)
7. Take possession of your lower receiver or firearm

Age restrictions also apply: you must be 18 years old to purchase a rifle lower receiver or 21 years old for a pistol lower receiver. Some FFLs may require you to be 21 years old for any lower receiver purchase due to the potential for pistol configuration.

State-Specific Shipping Restrictions

While federal law provides the baseline for what can be shipped to your home, individual states often impose additional restrictions. Understanding your local law is essential before ordering AR-15 parts online.

States with Additional Restrictions

State	Additional Restrictions	Key Requirements
California	Magazine capacity limits, “assault weapon” features	10-round magazine limit, featureless builds or fixed magazines required
New York	SAFE Act compliance, registration requirements	Fixed magazines or featureless builds, 10-round limit
Connecticut	Assault weapon ban, magazine restrictions	Pre-ban lowers only, 10-round magazines
Massachusetts	Approved roster, feature restrictions	Must be on approved firearms roster, 10-round limit
New Jersey	Assault weapon restrictions, magazine limits	Specific feature combinations banned, 10-round limit
Maryland	Banned features, registration	Heavy barrel required for certain configurations

Some states also restrict shipping of specific components. For example, New Jersey prohibits direct shipment of certain parts like flash hiders and folding stocks to consumers. Always verify current state and local laws before ordering.

Carrier-Specific Policies

Different shipping carriers maintain varying policies regarding firearm parts. Understanding these differences helps ensure smooth delivery of your AR-15 components.

UPS Policies

UPS generally accepts non-firearm parts for standard shipping. They require:

• No special labeling for parts (excluding receivers)
• Adult signature typically not required for parts
• Complete firearms and receivers must ship to FFL only
• Next Day Air required for handgun shipments

FedEx Policies

FedEx maintains similar policies with some variations:

• Parts ship via standard service levels
• No firearm-related labeling on packages
• Firearms ship only between licensed entities
• Overnight service required for handguns

USPS Policies

The United States Postal Service has the most restrictive policies:

• Long gun parts generally acceptable
• Handgun parts prohibited for non-licensees
• No handgun shipments except between FFLs
• Rifles can ship between individuals where legal

Building Your First AR-15: Component Shipping Guide

For first-time builders, understanding the shipping process helps streamline your build. Here’s a practical breakdown of ordering components for a typical AR-15 rifle build:

Direct-to-Home Components (First Orders)

Start by ordering these components that ship directly to your door:

1. Complete upper receiver assembly: Typically includes barrel, gas system, and handguard ($250-800)
2. Lower parts kit: Contains all small parts except lower receiver ($40-150)
3. Buffer tube assembly: Includes spring, buffer, and tube ($30-75)
4. Stock or brace: Based on your rifle or pistol configuration ($25-200)
5. Sights or optics: Iron sights or red dot to start ($50-500)
6. Magazines: Start with 3-5 magazines where legal ($10-25 each)

FFL Transfer Component

Order your lower receiver last, after confirming your local FFL’s policies:

• Stripped lower receiver: Requires FFL transfer ($50-200)
• Transfer fee: Budget $20-75 for FFL services
• Background check: May include state fees ($0-50)

Cost Comparison: Direct Shipping vs. FFL Transfers

Understanding the true cost difference between direct shipping and FFL transfers helps with budgeting your build:

Purchase Method	Typical Costs	Time Frame	Convenience Factor
Direct-to-home parts	$5-20 shipping	3-7 business days	High: delivered to door
FFL transfer (lower)	$20-75 transfer + shipping	5-10 business days	Medium: requires FFL visit
Complete rifle (FFL)	$25-100 transfer + shipping	7-14 business days	Low: wait times vary

Factor in these hidden costs for FFL transfers:

• Time off work for pickup during FFL hours
• Travel costs to FFL location
• Potential storage fees if not picked up promptly
• State-specific fees or taxes

80% Lowers: A Special Category

The 80% lower receiver occupies a unique position in AR-15 building. Currently, these unfinished receivers can be shipped directly to your home in most states because they’re not yet considered firearms. However, this landscape is changing:

• Federal definition: Not a firearm until 80% complete
• No serial number required: In most states (check local law)
• Completion requirements: Typically 1-3 hours with proper jig
• Tools needed: Drill press or router, specific jigs ($75-300)

Several states now regulate 80% lowers like complete firearms, including California, Connecticut, New Jersey, and others. The ATF has also proposed rule changes that would affect their classification nationwide.

What Are the Requirements to Get an FFL?

Some builders consider obtaining their own FFL to simplify the process. While not necessary for personal builds, an FFL offers advantages for frequent builders or those interested in the business side:

FFL Application Requirements

• Age: Minimum 21 years old
• Location: Compliant with local zoning laws
• Storage: Secure storage meeting ATF requirements
• Background: Clean criminal record
• Business intent: Must intend to engage in business
• Application fee: $200 for initial 3-year license (Type 07)
• Renewal: $90 every 3 years

Can I Have an FFL at My House?

Yes, home-based FFLs are possible in many areas, but require:

• Local zoning approval for commercial activity
• Separate entrance or dedicated business space preferred
• Secure storage (safe meeting ATF specifications)
• Ability to post required signage
• Willingness to allow ATF inspections
• Compliance with all state and local laws

Practical Build Recommendations

Based on shipping requirements and typical builder needs, here are optimized approaches for different scenarios:

First-Time Builder

1. Order all direct-ship parts first (upper, LPK, furniture)
2. Confirm function with dummy rounds
3. Select and order lower receiver
4. Complete FFL transfer while gathering tools

Multiple Builds Per Year

1. Establish relationship with local FFL for volume discounts
2. Order multiple lowers together to save on transfers
3. Consider C&R license for eligible items
4. Buy common parts in bulk when on sale

Budget-Conscious Builder

1. Compare total costs including FFL fees before ordering
2. Look for “transfer day” specials at local FFLs
3. Consider complete rifles if transfer fees are high
4. Ship multiple items together when possible
