Yes, but, young anon, room clearing is never easy or fun. I do suppose the best option to clean a room would probably be a short submachine gun with a high rate of fire, but this is not a good overall mix for an infantry rifle. My experience clearing rooms was with a suppressed M4A1, which was just as long as an M16 with a KAC NT4 hanging off the end of it. In any case, if I had to clear a room with an M16, I wouldn't feel terribly disadvantaged.
