AR-15s

Agreed. I had bought a Sig Sauer Romeo red dot, which is made by Holosun, it just felt too small looking through it. I replaced it with a Trijicon MRO, which then got replaced with an EOTech, but like you said, they are not cheap options, but I dont worry about them failing. I do have a set of Troy Industries flip up sights for backup, just in case.

Ive been shooting sig optics for 4 years now and had new clue they were made by holosun! With that being said, no issues with them in that time and I am pretty hard on my guns.
