The straight stock setup obviously raises your cheek higher than a sporter type stock, or those you see on the sks and m14. Iron sights, flip ups and carry handles are made to sit on the flat top where you will be mounting your optic and they sit about 1+ inches above the bore. Scopes are harder, because of eye relief, to get perfect height on but with a reflex sight as long as you get it up off the flat top you'll be fine. That being said I know some shooters who get a good cheek weld and just tilt their head forward to lower their line of sight to see red dots that are mounted right to the carry handle.
