IIRC,by bolt action I believe that they mean something more along the line of how you would manually cycle a semi auto.IOWs fire,bull bolt back,release,bolt picks up shell,fire,repeat.
Also,that link mentioned a weight less than an M203.It would seem hard to get prone in a hurry though,with that grip asm hanging down there.
