Firearms Unknown as Biden considers legislation restricting “ghost guns

FILE PHOTO: Polymer80 frame kits and upper receivers for Glock semi-automatic pistols are displayed for sale at Firearms Unknown, a gun store in Oceanside, California, U.S., April 12, 2021. Unfinished and inoperable so-called “80% receivers” are not legally considered firearms and do not require background checks to purchase in most states, but can be used to assemble un-serialized “ghost guns”.
