Input:
Have 5 sets of these rings in different heights and diameters.  They are the best low price mounts I've been able to find that are
made to decent tolerances.  Rail clamp and tube dimensions on every single one is spot on and they all hold zero down to better than 1 MOA.  They are a nice middle ground between the Chinese made junk and the $200-300 rings.
