2015

In August 2015 Leyonhjelm negotiated a deal to include a 12-month sunset clause on the temporary ban on importing the Adler lever action shotgun. The Government imposed the ban in July, while it reviewed the technical specifications of weapons in the wake of the Martin Place Siege.

A week prior to the ban lapsing as a result of the sunset clause, the Government reimposed the ban.

2016

During the 2016 Australian federal election campaign, Leyonhjelm attracted criticism after he suggested women's sport was not "interesting enough" to receive government funding, in response to Labor's proposal to increase the amount of women's sport broadcast on Australian television. Labor leader Bill Shorten responded, calling Leyonhjelm a "stone age man".

During the same campaign, the satirical television show The Chaser's Election Desk parked a campervan across the road from Leyonhjelm's house daubed in Wicked Campers slogans that Leyonhjelm had previously defended, with Leyonhjelm's name replacing derogatory references to women in the original slogans. Leyonjhelm reacted by threatening to call the police and told the Chaser team to "fuck off". He subsequently told women's rights activist Melinda Tankard Reist to "STFU" (for "shut the fuck up") when she accused him of hypocrisy.
