Well, the short answer is because it take more manufacturing know how to get all of those electronic down to a durable and reliable combat optic and the benefits of having a reliable and lighterweight optic can improve performance of an operator.    Sticker shock is always something that people have when they come in here and check out the pricing on Trijicon Optics like the RMR sights because they think that a small optic would be cheaper than a hunting or sniper scope.  Although the expensive stuff like Night Force and Leupold seem to be acceptable, paying $700 for a red dot like an Aimpoint T1 seem to be frowned on except for the people that are using them.  If you just pickup a scale and put down a Trijicon TA01NSN and compare it to an Eotech EXPS2-0 or the Aimpoint T1, you’ll seem there is a considerable weight difference and knocking off a pound of weight from your firearm and carrying more food, water, or ammo is far more important considering that Military Statistics show that most engagements are under 200yds and needing larger “reach out and touch someone” optics rarely occurs and normally there is a designated marksmen in a unit for that role with a different optic.

We really don’t have an option as to what is better, Aimpoint or Eotech, but you can’t beat the pricing and reliability of the Aimpoint Patrol Rifle Optics that comes with its standard mounting system.   We have picked up Bobro Engineering mounts for quick detach capabilities for some of the Aimpoint Optics, but there are those options with the Eotech Sights.   With Aimpoint you have night vision optics, with Eotech Combat Optics for your AR15 or M4 variant, you’ll need to know ahead of time and purchase a night vision compatible version of the sight.   Think about which type of batteries you want to have around whether you decide on CR123 batteries or AA Batteries, make sure you have storage units on your person, in your go bag, or on the AR15 Accessories like the pistol grip, stock extension ect and keep a few new condition batteries there.
