Swiss KUGS FATBOY Single-Shot Rifle -The Firearm Blog

KUGS is a firearms manufacturing company located in Geneva, Switzerland. The company was established in 2015 by a gun designer named Florian Kohli. Their latest product is a rather unusual-looking minimalistic single-shot rifle called FATBOY. The KUGS FATBOY rifle was designed to be a lightweight firearm for long-range shooting. Let’s take a closer look.

Swiss Firearms @ TFB:

The KUGS Fatboy rifle has an extremely simple and quite a strong design that will be available in a variety of calibers up to and including the .50 BMG. The action is locked via a laterally sliding breech block – similar to an artillery piece. The free-floated barrels are almost completely threaded externally to allow installing barrel harmonics tuning nuts. The barrels are also user-removable for ease of transportation and caliber changes. The lower receiver / trigger housing is made of 6061 aluminum. The stock consists of a pair of steel tubes and a composite buttplate. The LOP is not quick adjustable but it can be changed using different-length stock tubes. The overall weight of the configuration shown in the pictures (chambered in 7.5x55mm, with a 720mm (28.34″) bull barrel), is 3.450kg (7.6 lbs).

Here is a video showing how the KUGS FATBOY rifle is loaded and fired.

KUGS claim that the FATBOY rifle is extremely accurate. According to the company, the rifle has been tested with military 7.5x55mm SWISS (GP11) ammunition and at 300 meters (328 yards), it printed 1/2 MOA 5-shot and 1/3 MOA 3-shot groups.

I think an addition of some bipod attachment interface, a stock adjustment mechanism, a cheekpiece and AR pistol grip compatibility should not complicate the design too much but would definitely make it much more user-friendly.
