Gre-Tan Rifles LLC operates out of Rifle, Colorado and handles one thing exceptionally well: making rifles accurate. Owner Greg Tannel doesn't dabble. He won't touch shotguns, revolvers, or semi-automatic weapons. He won't do engraving or carving. What he does is precision rebarreling, accurizing bolt rifles and pistols, custom builds with both standard and custom actions, and stress-free bedding systems.
"If we can solve an accuracy problem for you, whether by building a custom rifle for any shooting discipline or accurizing an existing rifle, please contact us."
The core philosophy is simple: mass-market firearms are built to a price point, not a precision standard. For hunters, competitive shooters, and people who actually care about owning a fine rifle, that's not good enough. Gre-Tan rifles deliver that standard consistently through strict discipline and unwavering attention to detail.
Greg manufactures his own tooling for gunsmiths and enthusiasts—this isn't outsourced work. He understands the machinery and tolerances at a level most shops never reach.
