These devices and triggers that enable rapid fire, almost fast as a machine gun, are of no use to me. This includes bump stocks, binary triggers and forced reset triggers. They defeat the principles of aimed and contolled fire. I guess if you want one to shoot real fast, go for it. It's just not my thing. Unfortunately, these devices have been used in mass shootings, the most notable one in Las Vegas during the first Trump administration. That gives the AR-15 and similar platforms a bad stigma as killing machines.
That's a balanced response, and I agree with you to the extent the presence of 14 AR-15s, all of which were equipped with bump stocks in the Las Vegas mass shooting didn't make the AR-15 look good.
If I recall correctly, he fired almost 1050 rounds through 12 of the AR-15s in a total of 10 minutes before (his) shooting stopped, at a range of around 490 yards. He also fired a handful of .308 rounds through a few scoped AR-10s at a fuel tank at McCarran.
I'm not and never have been a bump stock fan, and I think ATF screwed the pooch when they allowed them in the first place.
In this case, the poor accuracy that goes hand in hand with a bump stock, made it suitable only for engaging an area target at that distance.
Reportedly a bump stock AR-15 can fire 90 rounds in 10 seconds (assuming of course you have a C mag). That's 540 rounds per minute not counting mag changes, and not to far off the cyclic rate for an M16. if it looks like a duck and quacks like a duck...
I didn't lose any sleep over it when the administration at the time banned them.

I'm a little kinder to binary triggers, at least well designed binary triggers where you an cancel the second "on release" shot. They do make for a very fast an accurate double tap and a very fast failure to stop drill in a personal defense weapon.
*If* you get the cadence down precisely *and* can maintain the timing, you can arguably put out about 400 rounds per minute with a binary trigger, but for the average shooter 200 rpm is more practical and that compares to around 100 rpm with a regular semi auto trigger.
More importantly, the binary function is selectable, and most people I know who have them do 95+ percent of their shooting semi-auto, once they get past the initial fun with it.
I do have one on my SBRd and suppressed MP5 home defense PDW. A need for suppressive fire isn't a high probability in what is already a very low probability occurrence, but like having a self defense hand gun or PDW in the first place, its nice to have the capability in the rare event you ever find yourself needing it.
I also wear a parachute when performing aerobatics. I have no reasonable expectation of ever bailing out, but if the need ever does arrive, I'm gonna need that parachute real bad and right now.
I'm also not going to say that no one should be allowed to have a parachute as they don't need it. Same with any self defense weapon.
