TRACK™ is a proprietary rifling known as Single Edge Polygonal (SEP). The primary
function of this innovation is to provide an improved rifling for a
gun barrel, which has a single edge area and a polygonal area separating the
grooves. In essence, it is a combination of standard and polygonal rifling.
This hybrid reduces any substantial deformation of the bullet due to its
minimal engraving. It allows the bullet to move more symmetrically along the barrel,
enabling a straighter line towards the target. Furthermore, the tighter seal of the
projectile reduces forward escaping gases, and therefore, minimal loss of gas pressures.
Ultimately, this design has the capabilities of shooting match grade ammunition at sub
MOA accuracy.
