I'm not sure that there is a whole lot to say other than what's written on their website:
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.

This is an upscale basic action with limited options so that production is faster and smoother. They handle nice as far as machine work is concerned, thread form is consistent. The rail is pinned and screwed (cheaper) and the recoil lug is pinned (cheaper). Saves time and money. For custom builds, it will hold it's value better than the Remington M700.
