The Casio EX FC150 is capable of capturing video at 30fps, 120fps, 240fps, 480fps, and 1000fps. Increasing speed decreases resolution. I've found that 240fps works best for most airgun shooting. 

 

If you want more information re: the gun, scope, bipod, or camera mount, please visit my channel page. There you will find videos covering those elements.

From "spdphotog" - "Take a look at the pentax UA-1 digital camera adapter looks similar and very available."

I've never used the Pentax mount, but I have used other products from Pentax and they usually make high quality stuff. Consider this model if you can't find the Seben, or if you simply think it looks like a nicer kit.
