One thing I noticed and that worries me is that when the safety lever is in the safe position and with the dust cover off, the lever will disengage and move all the way up when the trigger is pulled hard enough. I understand normally one wouldn't or shouldn't have any ammo loaded with the dust cover off, but still worries me.
The lever that engages the trigger in the safe position is slightly angled so that enough pressure is put on the trigger, and with the dust cover off to stop the lever from going up all way, it forces it upwards and releases the hammer.
