From the leaders in machining accuracy, Defiance Machine introduces the anTi X. Built for the outdoorsman looking for an action with integral rail/lug while coming in at an overall length typically only seen in a higher priced Titanium action. Weighing in under 26oz (Medium Action), the anTi X carries the same guaranteed headspace as the Ruckus or Tenacity line of actions.

Like everything Defiance Machine products, the new anTi X is built with a "no compromises" mentality to ensure the end user's expectations are exceeded.

    This is my second Anti X and I love them. I have put hundreds of rounds through the first one with no issues.

    Machine work top notch

    Posted by Dylan Aguirre on Apr 27th 2021

    The machine work of the defiance is top notch all the deburring process is immaculate the polishing is pretty excellent except for in the area where the Picatinny rail is machined down. I understand that polishers can’t reach in there very good because of the pocket but I did see some surface rust in there I had to address with some oil and Q-tips. Can’t wait to get the 7saum prefit carbon proof in and drop it in a gunwerks magnus stock! Should be an ultimate hunter cant wait! Not to mention a ZCO 4-20x. Should be a killer rifle that all starts with a great action thanks defiance!
