Well, let's see... how many ATR1000's are out there in the real world?? I'd guess a bunch... How many incidents are we hearing about??? Less than 10??? I don't know if there's a firearm out there that there hasn't been some kind of incident occur... If it's mechanical, sooner or later, something will go wrong. It could be user error, or it could be mechanical failure, or even mechanical failure due to user error.
I'm sure Remington, Winchester, Savage, Sako, Weatherby, Marlin, CZ, Browning, etc... pick a manufacturer, have had some kind of malfunction somewhere in their respective business lives... it's a matter of odds... sooner or later, the odds do catch up...
Cheers...
