Introducing TRACK™ 3.0 Barrels: Superior Performance and Unmatched Durability
At TRIARC Systems, we take pride in crafting barrels that surpass industry standards. Our TRACK™ 3.0 barrels are meticulously manufactured in small batches and undergo a rigorous quality control process to ensure optimal gas flow and reliable function.
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™ 3.0 barrels also feature an NP3® finish on the barrel extension that enhance the barrel’s resistance to wear. Furthermore, all TRACK™ 3.0 barrels feature a new contour: the balanced straight contour. This contour is a great balance between standard/lightweight profiles and heavier mid profiles.
****Coating Notes*****
NP3® metal finish offers many benefits. NP3® permits firing for longer periods of time between cleaning, dirt and powder residue have no wet or oily surface to cling to. When cleaning is required, the effort needed is minimal – usually requiring only a soft cloth. NP3® is very corrosion resistant. It provides a high lubricity and low friction co-efficient, greatly increasing the life expectancy of a firearm due to reduced friction wear. NP3® is a satin gray, non-reflective color ideal for all firearms.
USED – HUXWRX FLOW 762 Ti - SUPPRESSOR
Manufacturer: HUXWRX
Model: FLOW 762 Ti
Type: SUPPRESSOR
Caliber: 7.62
Reg. Overall Length: 6.77
The HUXWRX Flow 762 Ti harnesses Flow-Through Technology™ to minimize backpressure and gas blowback on .308, 7.62, and other 30-cal cartridges—all with no barrel length restrictions. This 3D-printed titanium suppressor weighs just 11.8 oz and measures 6.7 inches for a compact, lightweight form factor that excels on hunting rifles, carbines, and precision setups alike.
Engineered with HUXWRX’s torque lock mounting and a tapered fit, the Flow 762 Ti remains secure under rapid fire. Thanks to zero back pressure design, you can forgo gas adjustments, ensuring smoother operation on AR-10s, AK variants, SCAR rifles, and more. Whether you’re seeking a durable titanium suppressor for .308 or a flow-through can to tame piston-driven rifles, the Flow 762 Ti is a cutting-edge choice.

AXON SL Switch from Unity Tactical
As we put more, and more gear on our rifles it becomes necessary to streamline when possible. The AXON lineup of remote switches allow you to operate your lights and/or lasers with ease and this version of the AXON is the more minimalist model. AXON SL is the smaller, single button switch in the AXON family. It mounts directly to an M1913 Picatinny rail and features a 45-degree angled button face for an ergonomically correct activation angle. This makes it easy to index under stress, while wearing PPE or facing extreme environmental conditions. Molded from high-impact polymer, AXON SL holds up to abuse in the field. The mechanical switch design allows weapon light models to fire in both momentary and constant-on modes in a familiar click tailcap design. Laser versions utilize a momentary only switch to facilitate use with the native double-click-for-constant-on feature found in most common lasers on the market. Additionally, the AXON SL is available in single-lead and dual-lead variants for the most popular lights, lasers, and light + laser combinations.
