The internal components of the Legacy MKI Series of weapons systems are metallurgically superior due to careful selection of the highest quality, ordinance-grade BOSS 416R Steel, which was developed to exceed NATO specifications for military use throughout the world. Superior heat treatment processes are applied to each and every part, ensuring maximum efficiency and function. The rifling is a proprietary design known as the Caudle 3 system. It is based on segments of arcs forming a polygonal shape that increases the velocity of the projectile, reduces friction and results in less bullet deformation.
