Any suggestions on a cheap scope mount, or should I get taller rings.


The mount I use places centerline of the scope 1.3 Inches from the flat of the rails, it is comfortable for me to shoot standing, sitting, and prone. Standard AR sights are around 1.4 inches depending on the front post height.

Definitely cantilever, Cannot recommend a cheap one, all mine are Giessele which I can definitely recommend. I once dropped an AR about 36" and it landed in the dirt on the top turret. Nightforce scope and Geissele mount, never lost zero.
