Misc TM22 Dry fire with chamber flag

Since I got downvoted in a comment in a different thread, here is a video showing dry firing the TM22 with a chamber flag inside. Not sure if it can cause any damage, seems fine to me for occasional dry fire.

Why is it able to fire out of battery?

It actually wont have enough energy to set off the round with hammer follow

You sure about that? .22LR rimfire is notoriously unpredictable/unreliable. Proper hammer strikes 3 or 4 times, then it'll go off on the 5th. Who's to say with 100% certainty that a .22LR CANNOT detonate out of battery due to not enough energy in the hammer fall?

Because of geometry, the hammer fall on the bolt body rather than on the firing pin when its not in battery, and sometimes it have enough energy to hammer the round into chamber but you will only see a tiny mark, not enough to set off the round.

majority of semiauto dont have out of battery trigger disconnect because the other name of that is called auto sear.

None of my semi-auto .22's will fire out of battery. Not a one of them.

10/22 does, i don't know what other rifle you have but they mostly all do, majority of bolt action rifles and semi auto handguns do as well. they wont fire out of battery mostly but they will allow hammer/striker fall when bolt is not closed
