The following is how I would like to set up a .308 bolt action carbine, and while not meant as a direct criticism to the rifle forwarded by CanAm, I recognize that not all of my suggestions are practical or affordable on a mass produced rifle, but are suggested as possible improvements for folks who buy that rifle.
On the question of cartridge, I think it would be a mistake to initially bring the rifle out chambered for a reduced cartridge only, so I would object to the 7.62X39. A .308, 358, 7-08, .260 Remington, and a .243 will do things that the commie carbine round will not. When it is desirable to have a small game cartridge, or a light recoiling round for a child, a small adult, or a beginner, any of the aforementioned rounds can be down loaded appropriately, but you can't add more power to the 7.62X39. Of course my answer to "What is it for?" might be different than yours.
I think once a rifle barrel becomes much shorter than 18" the feel becomes clubby, and muzzle blast could become an issue. A lighter contour barrel than shown in the pic would be nice, perhaps culminating with a muzzle diameter of .590" and could shave a few ounces from the overall weight of the rifle.
My preference would be a ghost ring and post sight arrangement, with a means of mounting a scout scope forward of the action. Perhaps a long Picatinny rail would simultaneously provide a mounting option for a ghost ring sight, a conventional scope, and a scout scope.
I prefer a floor plate to a DBM, but if a magazine is the issue equipment, a second mag held in reserve under the butt stock, ala Styer Scout, would be a nice if expensive touch. If the floor-plate option was chosen, a rear notch for a stripper clip would be handy.
Due to the short fore-end length, the proper mounting point for the front swivel is on the radius of the fore-end to prevent a cut hand from the swivel stud. While this would omit a swivel stud bipod fastening point, I don't know if an ultra short rifle would be equipped with a bipod very often. If I wanted to mount a bipod on such a rifle I would consider an aluminum rail inletted under the fore-end.
