two recent examples : Trump pushes the ATF to 'redefine' bump stocks as machine guns - thus illegally creating a new law.

Biden bans ammo imports from Russian - the main source of 7.62x39 ammo - one of the most common rifle rounds in the US. This massively spikes the cost of ammunition.

Biden has also pushed the ATF recently to start more shenanigans with redefining things in relation to SBRs, Pistol Braces, and Supressor parts. It remains to be seen what effect this will have.

I can tell you aren't a gun owner of course but you might still find the ATF interesting. Basically they 'reinterpret' things as they see fit and thereby things that were legal become illegal (but almost never the other way around). Its a work around as they are basically creating new laws - however that is not legally a power assigned to them.
