The Smith Enterprise helical flute design blows away the flash suppression of the archaic straight flute designs. Smith Enterprise invented the straight flute design before any of these other companies. Smith Enterprise canned the straight flute design because it wasn't good enough. Instead, SEI went to the superior helical flute design that is curved and does a better job blocking the muzzle flash and gases. Additionally, SEI was the only design to win the CRANE Naval Surface Warfare .50 Cal solicitation that recently came out. The flash suppressors from various companies underwent very rigorous testing. Last point, the BE Meyers flash suppressor has a very weak case hardness (in the 20s) - meaning that it is highly unlikely BE Meyers heat treats his flash suppressors - meaning they are structurally weak and are not in accordance with MILSPEC. SEI's flash suppressors have a case hardness in the 30s. Additionally, SEI is the only company that puts a manganese phosphate coating on its suppressors making them much more rust resistant as well as rugged. So overall, these other flash suppressors are kiddie toys compared to the patented, and much sought after, SEI Vortex (R). It was so sought after that ARDEC let FHN steal the design! Unfortunately, SEI sued ARDEC and won.</p>SEIFri, 31 Dec 2010 01:48:00 -0000
