Cadex
Cadex Defence builds precision .50 BMG rifles for shooters who need the longest practical range a shoulder-fired platform can deliver — the CDX-50 Tremor and BMG Quake pair match-grade threaded barrels with fully adjustable chassis stocks built for serious long-range and anti-materiel work. Impact Guns carries Cadex’s .50 BMG lineup for extreme long-range shooters who have outgrown what a standard precision rifle can offer.

CDX-50 Tremor vs. BMG Quake: Choosing Your Cadex Rifle
The CDX-50 Tremor uses a folding chassis stock, letting the rifle collapse to a shorter overall length for transport and storage — a real advantage given how large a .50 BMG rifle is to begin with. The BMG Quake uses a fixed, non-folding stock with an adjustable cheek piece and length of pull, trading the folding convenience for a simpler, potentially more rigid platform. Both are available with a 20.6″ or 29″ match-grade threaded barrel, with the longer barrel giving more velocity and the shorter option trading some ballistic performance for a more manageable overall length.
Why .50 BMG? Understanding the Use Case
.50 BMG is not a general hunting or range cartridge — it’s built for extreme long-range precision shooting and anti-materiel applications, with terminal performance and effective range far beyond standard precision calibers like 6.5 Creedmoor or .308 Winchester. Buyers considering a Cadex should have a specific extreme-range use case in mind; ammunition cost and recoil are both substantial compared to any other common precision rifle caliber.
Chassis Stock Adjustability and Stock Color Options
Both Cadex lines ship with an adjustable cheek piece and length of pull, letting the rifle be dialed in for a consistent cheek weld and eye relief with a large day/night or thermal optic mounted. Cadex offers its chassis in black, hybrid tan, and olive drab green, matching whatever the rifle’s intended environment and role calls for.
Mounting Optics on a .50 BMG Rifle
Every Cadex rifle ships with a full-length Picatinny rail, giving enough real estate for the large, high-magnification optics typically paired with a .50 BMG platform, along with room for a bipod rail section or additional accessories forward of the optic.
Frequently Asked Questions
What's the difference between the CDX-50 Tremor and BMG Quake?
The Tremor uses a folding stock for a shorter transport length; the Quake uses a fixed stock. Both share the same match-grade barrel options and adjustable cheek piece/length of pull.
Is a .50 BMG rifle practical for general long-range shooting?
Not typically — .50 BMG is built for extreme-range and anti-materiel applications. Most long-range precision shooters are better served by a 6.5 Creedmoor or .300 PRC-class rifle for cost and recoil reasons.
Does a Cadex rifle come with an optic?
No — Cadex rifles ship as the rifle and chassis only; a scope and mount are purchased separately based on your intended range and use case.
