Rifle Scopes Vortex Razor HD LHT FFP 4.5-22x50 Review and Comparison to Bushnell ET LRHSi 4.5-18x44

Does down bias (20 MOA) change the 11.5 available up with a zero stop? Or is it a mechanical rev limiter?

The Rev stop system mechanically limits you to 2 revolutions of the turret.
It’s easily removed, not sure I’d want to do it in the field though.
