Not any comercially available ones that I've seen so far.
Most of the M42 to bayonet adapters are pretty much a plain metal ring 
with the M42 thread machined all the way through, which is probably the 
cheapest way to do it.
There are a few websites I've seen where some-one has hacked an adapter 
to push the stop-down pin in by glueing a ring onto the back of the 
adapter and this pushes the pin in as the lens is screwed into it.
