This is essentially the same way vortex does their zero stop and works just fine. Yeah its not as fancy and nice ass some of the higher end scopes but it works fine. The SWFA scope are just as stout as vortex so I really dont see how the turrets would be damaged as long as you didnt abuse them. Id like a set for my 3-15 and 20x mrad once you get a pricing structure lined out.
