Canon/Nikon Camera Rifle?

Ok, so I'm a pretty big photographer, and recently I've found some pictures and items like the ones pictured here of cameras with a stock and trigger like a rifle. The trigger actually works and takes the picture (i.e. You can see the wire on the top one) and the stock would help to steady the picture. I'm looking for something similar to one of these.
The top picture looks like an attachment for a regular camera which I can't find, and the bottom picture is a Fotosnaiper, an antique Russian camera that's no longer made or really sold.
I own a Canon Kiss Digital X, so it would be best if there was one for that, but I wouldn't mind upgrading cameras either.
A huge thanks to anyone who can help me out

There are some ready-made camera stocks, such as those made by SharpShooter, BushHawk, or Stedi-Stock.

So long as there's a 1/4 ³-20 screw to attach the camera with, you can technically mount a camera just about anything you desire. (You might have to be careful with your choice of stock/receiver, as some of these are classified as firearms.) Add a cable release, or make one yourself with some electrician skills, and you have a way of triggering the camera as well. You might even find some attachments normally used on assault weapons-such as laser sights, bipods, or foregrips-to be helpful.

Controlling zoom might be a problem, something the Fotosnaiper solved by integrating those controls into the stock. Another problem may be shooting in portrait orientation, though you could just hold the camera the intended way. So long as the cable release has "half-press" functionality, focusing shouldn't be too much of a problem.

You might also want some "safety orange" somewhere on the lens barrel, so those with real weapons don't mistake your camera for one.
