IMPACT STRESS = VELOCITY ²

“( the) cyclic rate, the higher it gets, of course, its is going to wear all the parts in a weapon, all the moving parts, because your impact loads go up, it is an energy function...the loads go up by the square of the velocity. If the velocity went up twice as fast, it isn ’ t twice the load, it is at least four times as much. In other words, you don ’ t pur a little more load on them. You put twice as much on them by running the cyclic rate up a couple hundred rounds a minute. ”

- Eugene Stoner (inventor of the M16)

FERFRANS RATE REDUCTION SYSTEM To increase reliability, parts longevity, and uncontrollability (in full - auto fire) of the M16 rifle, FERFRANS designed the Rate Reduction System (RRS) to re duce the rate of full - auto fire from 860 - 900 rpm to a much more controllable 580 – 680 rpm. This feature is unique to FERFRANS weapons. With such a re duced cyclic rate, burst fire or non - stop full - auto fire can be easily achieved by mere controlling one ’ s trigger squeeze to keep bullets on target, thereby in creasing accuracy. By reducing the rate fo fire in full - auto, the impact stress on the entire bolt group is also reduced, increasing reliability, parts longevity and resiliency to overheating.

FERFRANS SHORT - STROKE (EXHAUST TYPE) FULLY - ADJUSTABLE PISTON SYSTEM

FERFRANS rifles use a short - stroke piston system that is adjustable by releasing gas instead of the traditional “ choking the gas hole ” type. This system is capable of “ over the beach ” operations and fully adjustable for suppressed use.
