Cadex CDX-50 Tremor Action – for .50 BMG and .416 Barrett

The Cadex CDX-50 Tremor action is the heart of Cadex Defence’s .50 BMG and .416 Barrett anti-materiel and ELR rifle systems — a single-shot, bolt-action receiver machined to sniper-grade tolerances in Cadex’s Montreal facility. Built for the users who put rounds past 2,000 meters and need the action to deliver every time.

Full-length stainless steel receiver with integral 20 MOA Picatinny rail, oversized bolt handle, and a three-lug bolt engineered to tame the pressure curves of .50 BMG and .416 Barrett. The Tremor action is the platform behind Cadex’s CDX-50 rifles in service with military and law-enforcement precision units worldwide. Drop-in compatible with Cadex Strike and Tremor chassis systems.

This is a standalone action, ready to be paired with a Cadex or equivalent chassis, match-grade barrel, and the muzzle device of your choice. An ideal foundation for a dedicated ELR build, a clone of a deployed Canadian or allied precision rig, or a top-tier training/competition heavy rifle.
