ALL STEEL

Weighing as little as 23 oz.

As Defiance continues to innovate and find new ways to better serve our customers, we have pushed the envelope again. The anTi X is an ultra-lightweight action with integral scope mounts and recoil lug that shares the same guaranteed head-space measurement as our Ruckus, Renegade, anTi and Classic custom precision rifle actions. Using pre-hardened 416R stainless for the receiver and a 4340 chrome moly bolt, gives customers the smoothness, reliability and longevity that they have come to expect from Defiance.

Innovative weight reduction. Premium Materials. No compromises.

    Great Lightweight and Robust Action

    Posted by Christopher Ayres on Feb 8th 2025

    Great action for a Long Range NRL or Hunt gun. I chose this in conjunction with a MDT HNT26 for a 7 PRC build. Action is smooth as silk and functions proper like you’d expect from Defiance! There’s only a few lightweight but very sturdy actions for this type of rifle and this is #1. Great Action from a great company, Altus!

    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!
