The gas system is configured for subsonic rounds so the buffer slams home pretty hard when shooting supersonic loads. After about 1000 supersonic rounds and a few hundred subsonics the NFA lower looks and fits like when it was new. WebThe lower yield strength R eL is the lowest stress value in the flow range of the material following the upper yield strength R eH, whereby transient oscillation occurrences (e.g. due to a change in force) may not be taken into account.. In a case where the upper yield strength is not recognized (the reduction in force is less than 0.5%) or yielding occurs at a …
