Tru-Axis™ Precision Barrels are made using a revolutionary single-point rifling system in which one machine completely sculpts every portion of the barrel from start to finish. The rifling alone requires over one hundred and fifty minuscule cuts! This method is ultra-accurate and induces no stress that needs to be relieved later. The result is a barrel with absolute precision and rifling grooves that have a deviation of less than one ten-thousandth of an inch.
Tru-Axis™ Precision Barrels are entirely made in the U.S.A., feature a fully supported chamber body, and have an 11-degree muzzle crown. Each barrel is magnetic particle checked for microscopic cracks, hand polished then protected by a titanium-nitride coating.
Diamond-Like Coating
We have coated the barrels in an ultra-hard black DLC. To allow for a proper break-in and ensure the highest possible accuracy, the barrel’s bore and chamber are not coated with the titanium nitride coating that armors the outer surfaces (bore comes pre-oiled to prevent corrosion).
Threaded Option
Our threaded barrels feature a ½ – 28 right-hand threading that includes a thread protector cap. If you are using a threaded barrel, be sure to test your suppressor to recoil rod clearance before firing for the first time by slowly hand-racking the slide. The short threaded barrel gives .080″ more clearance for the recoil rod compared to the long threaded barrel.
