Special Operations Assault Rifle (SOAR) is an assault rifle manufactured by FERFRANS and designed as an improvement of the M4 carbine.
The SOAR is a selective fire 5.56×45 mm NATO assault rifle firing from either a closed rotating bolt (direct impingement) for the standard SOAR model, or in a short-stroke piston rotating bolt for the SOAR-P variant.
It differs from the typical M4 due to FERFRANS' preference to better control on full-automatic mode. Among the features include a patented Delayed Sear Activation System that reduces its cyclic rate of fire in full-auto to just around 550 to 680 rpm, reducing muzzle climb and improving control-ability. It also uses a heavy machine gun barrel for increased reliability in sustained firing, rifled in either 1:7 or 1:9 right-hand twist.
