From the Document: "The 117th Congress is considering two bills (H.R. 8 and H.R. 1446) that would amend the background check provisions of the Gun Control Act of 1968 (GCA; 18 U.S.C. §§921-931). The House passed nearly identical bills in the 116th Congress. [...] H.R. 8 would make nearly all intrastate, private-party firearms transactions subject to the recordkeeping and background check requirements of the Gun Control Act of 1968 (GCA). For a similar proposal, see S. 529. The House-passed bill in the 116th Congress was also H.R. 8. [...] H.R. 1446 would lengthen the amount of time firearms transactions could be delayed pending the completion of a background check from three business days under current law to several weeks. The timeliness and accuracy of FBI-administered firearms background checks became a matter of controversy following the June 17, 2015, Charleston, SC, mass shooting at the Emanuel African Methodist Episcopal Church. The House-passed bill in the 116th Congress was H.R. 1112."
