In looking closely at this rifle you can clearly see that this rifle could have very easily been the forerunner of the famous FN 49 and FN/FAL rifle designs as it has numerous similarities compared to those two rifles as follows: a hinged/split upper and lower receiver, a side mounted cocking handle that disengages from the bolt after it is cocked, a gas operated system that utilizes a long-stroke operating rod that directly cycles the bolt.

It also uses a very unique 'two-piece' hinged receiver type design. To release the bolt you pull the trigger, which allows the bolt to go forward and strips a new cartridge from the detachable box magazine. To initially load or charge the rifle it uses a fixed cocking handle on the right side of the action, that pulls the bolt to the rear and then disengages (from the bolt) and is pushed forward. The rear of the operating rod is connected to the bolt, so that when each shot is fired it cycles the bolt and cocks the action. This rifle was way ahead of its time as it has a gas operated system that uses a long operating rod mounted on the underside of the barrel, similar to the M1 rifle.
