Brandon, you will need a half inch riser to co-witness Sir. https://www.budsgunshop.com/search.php?q=riser&type=

For the AR platform, you will want to get either a 40 mm riser (which will provide 1/3 co witness, meaning the sights would sit in the bottom 1/3 of the optic picture) or a 37 mm riser (which will provide 1/2 or "Absolute co-witness", meaning the sight will sit in the bottom 1/2 of the optic picture).
