From The Federalist:

Section 2(f) of the Undetectable Firearms Act of 1988 (18 U.S.C. 922 note; Public Law 100–649) is amended— (1) by striking ‘‘EFFECTIVE DATE AND SUNSET PROVISION’’ and all that follows through ‘‘This Act and the amendments’’ and inserting the following: ‘‘EFFECTIVE DATE.—This Act and the amendments’’; and (2) by striking paragraph (2).

The provision looks harmless enough at first glance. However, to fully understand how this paragraph further infringes the Second Amendment, one must understand what the 1988 Undetectable Firearms Act says, and why striking the effective date puts our rights in jeopardy.
