I haven't got a clue what a "DROS" is, it must be a California thing. I do know what a Marlin 1894c is, and it's a great rifle. I have one with a 1.5X5 scope on it that has taken rabbits, woodchucks, deer, and one coyote. If you know your gun and your limitations, this gun will deal with anything that needs attention within 50 to 75 yards. Not loud as most rifles go and the bullet won't go into orbit if you miss.
