Arend Engineering designed and fabricated
this test receiver for Arend Rifled Barrels using
CIBRTMrifling technology. With this test receiver
and using diabolically loaded cartridges with
pressures that completely obliterate the brass case,
no detectable change in chamber or bore dimensions
occur in Arend rifled barrels using our rifling technology
and proprietary stainless steel.
Arend Rifled Barrels
Arend Engineering has developed a novel rifling technology for rifled barrels in both the process of manufacture and the internal geometry which provides superior sustained high rate of fire longevity and performance. This technology is so superior to the prior state of the art that it can not be patented by the US Patent and Trademark Office (USPTO) for fear of "secret patent" issue and loss of proprietary rights.
The ease of manufacture allows the application of a superior proprietary stainless steel of yield and ultimate strengths three times the strength of typical AISI 416, and 25% greater than AISI 4140 ChroMo steel.
