Statute-cited, last verified 2026-08-18
Restricted
Restricted. Possession of an unserialized unfinished frame or receiver is prohibited; lawful transfer requires a licensed dealer or manufacturer, serialization, and federal records. Effective 2022-06-30.
Controlling law: 11 Del. C. § 1459A
Contested entry
The statute reaches the unfinished component itself and makes knowing possession without the manufacturer's name and an individual serial number a class D felony. A serialized unfinished receiver can move through the licensed channel, so the state is restricted rather than a categorical ban on all unfinished receivers.
Federal law
Federal law does not prohibit making a firearm for personal use, but prohibited-person, detectable-firearm, and unlicensed manufacturing-for-sale rules still apply. On August 17, 2026, Defense Distributed v. Blanche held 27 C.F.R. §§ 478.11 and 478.12(c) unconstitutional, but the judgment did not vacate those regulations and its declaratory and injunctive relief is party-scoped. Buyers outside the protected parties remain subject to the 2022 federal frame-or-receiver rule while litigation continues; state serialization, transfer, possession, and manufacturing laws apply independently.

What to buy
In a restricted state, start with a factory-completed lower carrying the manufacturer's serial number and complete the required dealer transfer. These are serialized receivers, not unfinished 80% lowers, pistol-frame blanks, or do-it-yourself receiver kits.
