The SOAR incorporates modifications and improvements to the M4 rifle that will among other things ensure enhanced reliability, accuracy, firepower, zero retention, ergonomics/ man machine interface, overall parts longevity, and increase service life.  By incorporating the patented Independent Sear Disconnector reduced the cyclic rate of fire in full auto below 700 rpm.  This allowed the weapon to be totally controllable in full-auto, reduced impact stress on the parts, increase accuracy and firepower, reducing the heat and increase the resiliency to cookoff, increase parts longevity and overall service life.

The soar P (Piston version of the soar),  further increase the benefits of the SOAR by changing the gas system with a short stroke piston system with the independent sear disconnector enhancing the capability of the rifle to fire without draining the water in “over the beach” operations.

The main feature of the FERFRANS SOAR is its patented Delayed Sear Activation System. It is a me- chanical device that reduces the cyclic rate of full-auto fire of the M16 / M4A1 type rifles from 850-900 rpm to 550-680 rpm. This system does not only reduce the cyclic rate of fire but also reduces the veloc- ity (Impact Stress) of the bolt carrier assembly as it goes into battery making the rifle very controllable and smooth in full-auto fire. Reliability is increased because impact stress is reduced considerably and heat is reduced. Burst controlled fire can be achieved with just a simple squeeze of the trigger as the time between shots are slower and the tempo is constant. The effect is immediate – Controllable Accu- rate Full-Auto Fire. Another advantage of the RRS is for short barreled rifles and the use of suppressors.
