A tad bit loose - Vortex Defender Flip-Cap Lens Cover

Great construction, materials. Have them on three Vortex scopes matching to Vortex's fit specs for each scope. Used Butler Creek in the past and they worked very well on Leupold scopes. Thought these would be the optimum for the Vortex. Would be five stars except..... they will not stay in place when opening. Both ends on the Strike Eagle do not fit tight enough to insure opening does not include complete removal from the scope or at minimum displacement enough to require re positioning. On the PST Gen II 1-6 they work a little better and would give them four stars on that scope. The third set is on the older 5-20 Razor and they get four stars on that scope as fast acquisition is not as critical. The material in the Vortex caps is superior to the Butler Creek caps and the Vortex seal better from the elements. The superior seal is perhaps the Achilles heel in that it is responsible for the displacement when opening the caps. If the cost was per Butler Creek I might raise the rating but I was willing to pay the extra cost for a better looking (which the Vortex are) and better fitting (not) than other caps. One could wrap some tape at both ends of the scopes to attain the tighter fit desired but that should not be required.
