About Mark Robles

THE ORIGIN OF ACCURACY

Radix — the root, the origin — is where accuracy starts. After countless hours studying ballistics and the craft of the precision rifle, owner Mark Robles turned that obsession into a gunsmithing operation built on one standard: every build receives the same care and uncompromising attention to detail, whether it's destined for the hunt, the range, or the competition stage.

Every component passes through one set of hands. No shortcuts. No farming out. Our work has contributed to match wins across numerous shooting disciplines throughout the United States — and found its way into the hands of competitors internationally.
