Thanks Bob,
You can add a bipod, but the problems arise when you zero it.
The springer likes to move in its own free ways (usually forwards and backwards)
If you add a pod to it, the thing is very likely to jump upwards and off to one side, as well as forward and backwards.
This itself is not a problem once you have worked out your zero properly when shooting from the pod.
BUT when you try to shoot in any other position, your rifle will go its own merry way again and your going to miss the target by quite a margin.
So I would deffinately avoid putting a pod on a springer.
