If you have a Sightmark, you have a Reflex sight NOT a Holographic.
The Advanced Combat Optical Gunsight, or ACOG is made only by Trijicon (ACOG is also a registered trademark).
You can get something that looks it but you won't get the real thing unless you get a Trijicon.
(it is sort of like saying "what is the best brand of Kleenex?" ... Kleenex IS the brand, the product is a tissue)
So if you need a high quality optical for the AR and it must be an ACOG you will spend $1000-1500 or you can get any number of quality optics suited to the AR platform for $300-600.
If you just want the tacticool look to shown your pals from COD, you can go to Midway USA and look at the Bushnell, Barska or Leapers, I know NCstar also makes a look alike. Most of them are a waste of money for a serious shooter.
