Expecting a Thureon in the mail in the near future and am confused about what type of sights are available. I'm guessing AR 15 type sights but in reality I know very little about AR's or sighting systems for the TD. I've done searches on this but keep coming up with term like BUIS, gas block sights and such which does not compute. Anyone want to help out a fledgling in understanding this stuff and what might be suitable for the TD?
