An Act amending Title 18 (Crimes and Offenses) of the Pennsylvania Consolidated Statutes, in inchoate crimes, further providing for prohibited offensive weapons.

HB 1866 would have expanded Pennsylvania's definition of "prohibited offensive weapons" under criminal law to include specific items like modified firearms and certain knives, making it a crime to attempt to obtain or possess them. The bill aimed to clarify that inchoate offenses (such as attempted possession) involving these weapons would be punishable under existing statutes. It directly affected individuals facing charges related to preparing to obtain or carry these weapons. However, the bill was defeated during final passage on October 1, 2025.
