Comments about Telrad Telrad Spare Mounting Base:
This is cheap insurance. you can add one to each of your scopes and know that your Telrad will go on any of them. You dont have to have a Telrad for each scope even though it is good to have more than one, just in case. They use a wedge and two screw type mount so they are very easy to use. you can put them on with your tape (tends to stretch), the two sided tape already on it, or bolting it.
