What we doGet in touchWhat we do
From a single repair to a ground-up build, every job gets careful measurement, clean machining and a finished product you're proud to carry.
Custom builds
Rifles and pistols built to your purpose, budget and taste — from component selection through assembly, fitting and finish.
Gunsmithing
Repairs, tuning, fitting, upgrades and restoration. We diagnose the problem, explain the fix and get it running right.
Machine shop & precision work
Precision machining for parts, fixtures and fine adjustments — the measured, repeatable work that accuracy depends on.
Built for how you shoot
Every build starts with how the gun will be used.

The name says it: in this work, accuracy comes down to the diameter — getting the small dimensions exactly right.
