I know you said "no magnification," but this gives you that option should you decide later a little magnification might help out Nice crosshair--kind like a German #4 with the ability to illuminate if needed. $120--not a bad deal. I'm thinking I might go that way if I ever get another upper (18-20" for yotes, a 16" with this scope for closer in work).
