MODERATE
The bill was reformatted from a substitute version to the version passed by the Senate, which includes significant text corrections and clarifications. The most important substantive change is the addition of 'multiburst trigger activators' to the list of prohibited items, alongside existing bans on machine guns, bump stocks, and silencers. The text also fixes several typos, such as correcting 'peoplE' to 'people' and removing redundant words like 'that' and 'Secretary' to improve legal clarity.
Scope change
The scope of prohibited items was expanded to explicitly include 'multiburst trigger activators,' broadening the ban on devices that increase the rate of fire of semiautomatic firearms.
REQUIREMENT
Added 'multiburst trigger activator' to the list of banned items in subsection (1)(g).
DEFINITION
Corrected the title and header text to match the final Senate version, removing placeholder formatting.

TECHNICAL
Fixed multiple typos and grammatical errors throughout the text, including correcting 'peoplE' to 'people' and removing redundant words like 'that' and 'Secretary'.
