I have the same gun in 24 and 20" and love them both. Super accurate and reliable. I happened to have a Leup AR 6-18x40 with Mildot ret. that just rocks. I have it sighted at 100 and with the first dot, dead nutz at 300. Don't have access to further ranges but really simplifies it. I think with Strelok I am using 16x. Pretty sure But love the setup.
