There are plenty of options to think about when you are putting an optic on  your AR15, and i’m going to assume that this is why you are hear reading about this blog.   There are Eotech sights like the 512 which are combat reliable and not very expensive, and if you shop around, you might be able to pick one up for under $400.   The Aimpoint optics are also extremely durable and the Aimpoint Pro are under $400.   Magnification is the biggest thing you really want to think about from the start.  If you think you will be able to cough up the money for an RMR sight in the future, then a TA01NSN might be a nice starting point because you atleast get 2 sights in one.  Iron sights for close up fighting and a 4x fixed optic with bullet calibration.

I know a lot of guys that run the TA01NSN because they don’t like the fiber optic strands that run across the top, those are considered to be high profile and not low profile optics.    I would probable say that the Trijicon TA01NSN for sale is the most verstatile ACOG because you get the 2 sights in one, plus you have the illuminated reticle in low light.   Some people, or should i say many people, prefer the crosshairs of this reticle type over the Chevron or the donut styles.  All reticles have a primary job and some are more versatile than others.  The thin lines of the TA01NSN make it a very precise optic.   The ones we sell all come with a thumb screw mount and if you want to later on, do some research into which type of RMR sights you might want to run on your gun.  The red dot and reticles are very different so  do your research and read reviews on the product.
