TRIARC Systems - 16" SPR Track 2.0 Barrel KIT 5.56mm

These barrels are done in small batches and go through an extended QC process to ensure proper gassing and function.

Introducing TRACK™ 2.0 barrels, exclusively from TRIARC Systems. 

TRACK™ is a proprietary rifling known as Single Edge Polygonal (SEP) available through TRIARC Systems. 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 toward the target. Furthermore, the tighter seal of the projectile reduces forward escaping gases, and therefore, minimizes loss of gas pressure. Ultimately, this design has the capability of shooting match grade ammunition at sub MOA accuracy.

As an evolution of this barrel, TRACK™ 2.0 barrels also feature an NP3® finish on the barrel extension that enhance the barrel’s resistance to wear. Furthermore, all TRACK™ 2.0 barrels feature a new contour: the balanced straight contour. This contour is a great balance between standard/lightweight profiles and heavier mid profiles.
