TRIARC Systems TRACK 2.0 5.56 Mid-Length Barrel - 12.5"

Use a cutting edge barrel in your next AR build. TRIARC Systems has developed a proprietary rifling that blends the best of both standard and polygonal rifling. This TRACK 2.0 barrel has a single edge area and a polygonal area for separating the grooves.

Features:

• Chambered in 5.56 NATO
• 12.5" length
• Mid-length gas system
• NP3 coated barrel extension
• Single Edge Polygonal rifling
• Black Nitride barrel finish
• 1:7 twist rate
• 4150 CrMoV barrel steel
• .750" gas block shelf
• 1/2x28 threaded

The advantage of this rifling -- known as Single Edge Polygonal (SEP) -- is a significant reduction in the engraving on the bullet as it travels down the bore. This reduction in deformation means the projectile retains a more symmetrical shape, allowing for increased accuracy. The reduced engraving on the bullet has the added benefit of reducing the loss of gas pressures, which helps with retaining velocity. 

Bottom line: You can get sub-MOA accuracy with match grade ammunition in the TRACK 2.0 barrel.  

Shoot longer without having to worry as much about cleaning your barrel. TRIARC Systems TRACK 2.0 barrels include a low friction NP3 finish on the barrel extension. You know the TEFLON that makes your frying pan non-stick? The same compound, known as polytetrafluoroethylene, is combined with electroless nickel to create the NP3 finish. 

Not only is this finish more corrosion resistant, but it also increases the lifespan of your barrel by reducing friction. Cleaning it is a snap. Sometimes you can do it with just a soft cloth.

If you’re looking to build a high-quality 5.56 pistol, this 12.5 inch barrel is an excellent choice.
