the m4/m16/ar15 shoots like a .22 squirrel hunting rifle really just with a louder bang. honestly i'd prefer the ak because of its durability...and you are absolutely right about the thing jamming at the worst times. happened to me at qualification, you have to constantly clean it even when you don't use it. and i hate when they make us train with blanks because that is a pain in the ass to clean out.
