Sexy Action by Defiance Machine – The Ruckus

    Earlier this year we proved that an action on its own can be sexy. It is now time again, as Defiance Machine release their Ruckus action in a Remington 700 footprint.

    The new Ruckus bolt guarantees a headspace tolerance of +/- .001” action to action, and I don’t think I’m alone in appreciating when things are both made with the best tolerances and look good at the same time.

    The new action is available in Tactical, Hunter, GA Hunter or an Ultralight profile.

    As described by Defiance Machine:

    When I see this action I am tempted to start building a really nice high-end rig for Long Range Precision Rifle shooting. What about you? Do you like what you see?
