Vortex Throw Levers

Update: I found the thickend section for the screw in the V1 model intefered with my bolt handle when in the low magnifications. Enter the V3 where this portion was moved to the top and out of the way.
The levers seem to fit most Votrex scope adjustment rings, the V1 has been confired to fit the Viper (PST and non PST) models as well as the DIamondback Tactical.

These are two designs I'm playing with to design a scope throw lever for the diamondback tactical that is sufficiently robust for use.

First attempt will be to thread the m3 fastner straight into the plastic, will likely work better on the "V1" as as stresses are carried by the keys and fastner is only to hold it on.

Test of the V1 model is successful, although it requires some effort to get the screw to form threads directly into the plastic, dimensions were altered to achieve a comfortable fit around the screw. Using a tap to form the threads would be advisible if one were available to you
