Also known as: Defiance Tenacity, Tenacity Action
Overview
The Defiance Machine Tenacity is a precision bolt-action rifle action platform that has become one of the most popular foundations for custom PRS competition and precision hunting rifles. Sold primarily as a complete action rather than a finished rifle, the Tenacity is built from pre-hardened aircraft-certified 416 stainless steel with an integral recoil lug and a one-piece 4340 chrome-moly bolt featuring recessed locking lugs, a mini-16 extractor, and plunger ejector. The action guarantees a headspace tolerance of plus or minus 0.001 inch from action to action, providing exceptional consistency for precision shooting. Designed to fit the Remington 700 footprint, the Tenacity is compatible with the vast ecosystem of stocks, chassis systems, and accessories built for that platform. Complete rifles built on the Tenacity action by custom builders and by Tenacity Arms typically weigh 6.4 to 7.0 pounds in hunting configurations with Proof Research barrels, or 14 to 17 pounds in PRS competition builds. The action is available in short and long configurations with multiple bolt face options to accommodate calibers from 6mm GT to 7mm PRC and beyond.

Notes
The Defiance Machine Tenacity is primarily sold as an action, not a complete rifle. However, Tenacity Arms and numerous custom builders offer complete rifles built on this action. Area 419 also offers Tenacity barreled actions with Proof Research barrels. Starting at $885, the Tenacity offers premium action quality at a value price point. The Tenacity 2.0 updated version features refinements to the bolt and receiver.
Background
The Defiance Machine Tenacity democratized precision rifle building by offering action-to-action headspace tolerances of 0.001 inch at a sub-$1,000 price point, a level of consistency previously available only from actions costing twice as much. This made it a favorite among custom builders and PRS competitors seeking repeatable precision without premium pricing.
