The FERFRANS SOAR is a selective fire5.56x45mm NATO assault rifle firing from a closedrotating bolt. It has a gas-actuated piston-driven long stroke operating system, which uses burnt powder gases vented through a port in the barrel to power the weapon's moving parts. It uses a heavy machine gun barrel for sustained firing to produce a sub-machine gun with a high power caliber. The FERFRANS SOAR uses a unique patented rate reduction system (FERFRANS RRS) that reduces the cyclic rate of fire regardless of barrel length. This allows for controlled bursts without the use of a burst fire setting. The combination of the low cyclic rate, a compensator, and Selective Integrated Rail (S.I.R.) with vertical foregrip permits sustained automatic fire with no muzzle climb, making the weapon extremely controllable, and capable of overwhelming and accurate firepower.
