A mixture of the traditional barrel making with a blend of modern science. We utilize the absolute state of the art machining equipment and practices in the production of your barrel. Only the best barrel makers use these processes.
We start with solid stainless steel (BOSS 416R) bar stock imported from Germany. double stress relieved, polymer quenched, ingot cast, low delta ferrite, DFARS complaint and absolute temperature controlled material.

In preparation the bar is trued, squared and inspected for uniformity.
Drilling is accomplished with WWII Pratt and Whitney machines and state of the art computer controlled drills, utilizing cutting fluids individually blended for us. The bars are inspected for hole straightness and size before heading onto further processing.

Precision reamed on machines of our own design, with precise construction, we hold to a tolerance of .0002”.
After reaming we employ a few other process to ensure a the most accurate barrel possible.

Rifling is accomplished on computer controlled machines where we can control any given twist rate and rifling form. We use our Polygonal Caudle in P3 or P5 rifling known for its accuracy. Once rifled, we subject the barrels to a number of processes to ensure the stability and accuracy we are known for.
