TRIARC Systems 11.5" TRACK 2.0 5.56 Nato Barrel Kit

A New Standard for Rifle Performance

The TRIARC Systems TRACK 2.0 Barrel Kit is the ideal solution for enhancing the performance of your rifle. This kit includes an 11.5" TRACK 2.0 Barrel optimized for the TRIARC Systems A5/Extended Receiver Extension, VLTOR A5 H1 Buffer, and Sprinco Green Buffer Spring. The package also contains a Mil-Spec End Plate and Castle Nut. The result is a rifle that shoots flatter and operates similarly to a factory gun from TRIARC Systems.

Unique TRACK™ Rifling

TRACK™ is a proprietary rifling innovation unique to TRIARC Systems. It combines standard and polygonal rifling, offering a single edge area and a polygonal area that separates the grooves. This hybrid design minimizes bullet deformation, enabling a more symmetrical movement along the barrel, and ensuring a straighter line towards your target. The improved seal minimizes gas pressure loss and allows the barrel to shoot match grade ammunition with sub MOA accuracy.

TRACK 2.0: The Next Evolution

TRACK™ 2.0 barrels stand out with an NP3® finish on the barrel extension, increasing resistance to wear. These barrels also introduce a new balanced straight contour, providing an optimal balance between standard/lightweight profiles and heavier mid profiles.

Advanced NP3® Coating

The NP3® metal finish offers numerous benefits. It allows for extended firing periods between cleanings, provides high lubricity and low friction, and increases the life expectancy of a firearm due to reduced friction wear. The satin gray, non-reflective color is ideal for all firearms.
