The Starrett 120 6" Black Face Dial Calipers bring precision measurement to your gunsmithing bench, reloading setup, or precision shooting workshop. Built as an American-made alternative to imported dial calipers, this tool delivers the accuracy and reliability that gunsmiths, armorers, and reloaders depend on when tolerances matter. Whether you're checking chamber dimensions, verifying case neck thickness, or measuring component fit during rifle builds, the 120 Series gives you confidence in every reading.

What sets these calipers apart is their design for real work: the knife-edge contacts handle both inside and outside measurements with equal precision, while the thumb-operated fine adjustment roll lets you dial in exact measurements one-handed—crucial when you're holding a part steady with your other hand. The hardened stainless steel construction across the bar, measuring surfaces, rack, gears, and depth rod resists wear and corrosion, so these calipers will outlast the projects they measure.

The 0–6" range covers most gunsmithing tasks, from chamber checks to barrel measurements, while the .001" graduations give you the resolution needed for ammunition and firearm components. The sharp, clear black face dial is easy to read in shop lighting, and the direct-reading scale eliminates conversion math—just turn and read. If you're serious about precision work, American-made quality tools like the Starrett 120 pay for themselves in confidence and consistency.
