You can bump fire a whole bunch of rounds inaccurately down range without a bump fire stock.
Just depends on how you hold and fire the gun.
Personally I like to aim my shots, and I don’t wish to melt my barrel either.
There are plenty of videos on YouTube that show a barrel melt down, not as easy as you might think. Think about shooting into a wall, is accuracy really the most important thing to you?
Same here - spent years competing with, and beside, my Dad...one well-aimed shot can literally be worth 100 sprayed....and maybe even more.....especially as the distance increases when it comes to actually hitting a specific target...
