This Act was intended to clarify three areas of firearms law in the Bill stage. All 3 amendments were to section 5 of the 1968 Act. Firstly was the prohibition of bump stocks. This was a reaction to the 2017 shooting spree at the Mandalay Bay in Las Vegas. Lever release firearms were also moved to s5. They are effectively a semi-semi-automatic in as much the bolt stays open on a shot but is closed with a convenient lever, thus speeding up the rate of fire . The final item for consideration were high muzzle energy firearms. Although targeting 50BMG rifles the "capable of 10,000 foot pounds of muzzle energy" also could apply to some British hunting rifles on their proof energies. This proposal never made the final Act. There were several proposed amendments to include further restrictions on all firearms and the licensing of non-dangerous air weapons in England and Wales, again none getting enacted. Air weapons and high muzzle energy firearms were also part of a public consultation in 2020.
