No not really. because like I said, it works at ranges where ADS isn't liked because the enemies are too close and can easily move round your sights, but not close enough that hip firing is 100% reliable

Exactly, PUBG put in a system like this, where holding the aim button steadied a hip fire aim, and tapping it toggled ADS. Though I wouldn't say this was executed well since the accuracy of most weapons in that game is pretty bad......like the sound design

Well no, they don't HAVE to be. Iron sights aren't always gonna be better than nothing. And like I said, this bug's aim bridges a gap between the range where you don't wanna aim at all, and when you wanna aim with your sights. It's really preferable over using the iron sights when the enemies are too close for it to feel right but not close enough that you're confident that hip-firing would be just as effective. I spoke to some people in the Discord about it yesterday and they actually seem to support the bug and the idea of it becoming a gameplay feature.

After using the M60 for a bit of time, I came across what I can assume is a bug. I noticed that occasionally whilst fighting hordes, when I aimed it would zoom in and steady my aim like I was aiming, but without actually looking down the weapon's sights. Eventually I found out how to recreate the bug very easily by just double tapping right click. I'm not sure what other weapons this may work on but I know it doesn't affect the auto-shotgun, SMG-9 and Desert Vulture. Adding and removing the attachments on my M60 doesn't seem to affect it but I actually rather like it to be honest. It has all the penalties and buffs of regular aiming just without the iron sights so it's not technically an advantage but it's fits very nicely when steadying the aim on close targets and I think all weapons should have this ability.

Just don't eat it? And make sure you're pressing the right key next time?
