Are Ghost Guns and 80% Lowers Legal in Maryland?

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.

Federal baseline verified 2026-08-18. Scope: Unfinished firearm frames and receivers, including products marketed as 80% lowers or pistol-frame blanks, plus firearms privately made without a serial number. Serialized stripped receivers transferred as firearms are outside this class's unfinished/unserialized restrictions.
