Don’t play stupid bro I specifically assault weapons or let me dumb it down assault rifles not automatic handguns… now to answer the last part of your question yes the only guns civilians should possess is handguns, hunting rifles and shotguns… Why do civilians need AR-15s and M4’s?
Noone has sutomatic handguns
And plenty of ppl decided to have an AR 11million of them are in circulation and ppl use them for hunting and varmint control
Again seems to me since you're using incorrect terminology and making presumptions about what ppl need and don't need ...
Probably why what you're proposing sounds so ridiculous
You don't know what you're talking about when it comes to guns ( obviously ) and this is why so many ppl who propose controls- how are you gonna make proposals about what other ppl need when you don't even make the effort to learn about the thing you want to regulate more
The lower receiver doesn't have to tolerate any heat or pressure - its a lower receiver - the the heat and pressure occurs in the upper which you can put together easily from parts you can buy anywhere online or at gun shops
