Highly unlikely, and negligible compared to what happens during a normal cycle of operations:the extra impacts from bolt bounces cause NO additional damage or wear
Compared to when the ejection port is fully open during the cocking phase, it is negligible. If debris entering the weapon during the cycle of operations, or because of bolt bounce, caused the weapon to malfunction (not jam), I would imagine that weapons maufacturers would have developed a different design by now.....most of the debris that gets in to the upper, gets there during reloading. Either through dirty magazines or through debris inside the magazine that sticks on the ammunition.bolt bounces do NOT allow ANY additional opportunity for debris ingress/jamming
Also, when you are talking about the hammer engaging the "disconnector" during fully automatic fire, you are actually talking about the full auto sear, right? Because it is physically impossible for the hammer to engage the disconnector during full automatic fire. When the selector is put on full automatic fire, a cam on the selector axle lowers the rear of the disconnector, pushing it out of the way of the disconnector notch on the hammer. If the hammer engages the disconnector, there is something wrong with the triger mechanism, not bolt bounce. As far as bolt bounce causing the hammer to be caught by the sear on the hammer notch.....not plausible, as there would have to be a lot of movement. Actually, it is not possible as long as the trigger is depressed with the selector on fully automatic fire. The hammer notch will not engage the sear.
ETA: With the selector on full auto, there is a 2 cm gap in the ejection port before the hammer engages the sear when I pull the charging handle to the rear. The gap is even bigger, maybe 3,5-4 cm, before the disconnect engages the hammer, with the selector on semi auto.
