The CDX-50 Tremor action is a massive action at almost 12” long and 2” in diameter, precision CNC machined from a solid piece of stainless steel. The CDX-50 action was designed from the ground up to offer extreme accuracy and consistency not seen before in a 50 BMG-sized action. Our 4-lug design and 50-degree bolt throw is the fastest running bolt on the market in this class of actions. Combine this with a Cadex-designed firing pin assembly for faster lock times, oversized extractor, and double ejectors, for an action that can handle the demanding needs of military and targets shooter equally. The CDX-50 is a proprietary Cadex footprint, we do offer a CDX-50 bottom metal for traditional stocks as well.
