I am going to hunt with the simple firedot duplex, if the red dot is on why do you need the #4? For a self defense rifle an aimpoint or Eojunk is all I can see myself needing, beyond their range it would be some serious serious chit goin on and feeble old dudes like me need not apply anyway. Anyways, I am seein most of my shootable deer these days at very first and very last legal light, too much hunting pressure I think.
