Tenacity Actions: Defiance’s Superior Quality at a Great Value

Defiance is known for superior quality, innovative design, and cutting-edge manufacturing. Many of the designs and new products come from listening to customers. Since some shooters and hunters don’t always need custom options, Defiance is introducing a well-designed, precision rifle action at a great value.

Using new machining technologies and a clever design, this action has the precision and quality customers expect, but with a significantly reduced price.

The Tenacity is machined from the same steels and to the same tolerances as the Rebel and Deviant. Limited options (see below), but a versatile design that delivers either on the range or deep in the wilderness.

Each Tenacity action includes either a 20 MOA stainless steel Picatinny scope rail, or a pair of Talley Manufacturing one-piece Lightweight Alloy Scope Mounts. It’s your choice!
