CADEX CDX-50 Tremor 50 BMG 20.60″ 5+1 Folding Tan Stock
About this product
What is the CADEX CDX-50 Tremor 50 BMG?
The CADEX CDX-50 Tremor is a bolt-action .50 BMG precision rifle built to military specifications designed for extreme long-range engagement with heavy-for-caliber projectiles. It combines match-grade barrel threading with a DLC-coated aluminum receiver and folding stock system that transitions from 34.40 inches to 43.10 inches depending on configuration. This platform delivers repeatable sub-MOA accuracy at 1,800+ meters while maintaining transportability uncommon in .50 caliber systems.
What is the CADEX CDX-50 Tremor used for?
The Tremor serves as a dedicated long-range precision and anti-material platform capable of engaging targets beyond 1,500 meters with specialized ammunition. Its 20.60-inch match-grade barrel and 1:15 twist rate stabilize heavy projectiles like the 750-grain AMAX, while the 22.70-pound weight provides stability for precision shots without requiring a full bipod system. Civilian applications include ELR competitions, rangefinder-verified distance shooting, and regulated Title II destructive testing under NFA compliance.
How does the CADEX CDX-50 Tremor compare to the Stevens 334 Rifle?
The Tremor outperforms the Stevens 334 Rifle in maximum effective range and anti-material capability but requires specialized transportation and NFA consideration. Where the Stevens 334 in .308 Win reaches ~800 meters effectively, the Tremor’s .50 BMG chambering and 20.60-inch barrel achieve consistent impact at 1,800+ meters with 40% heavier projectile energy retention. However, the Stevens 334 weighs 7.3 pounds compared to the Tremor’s 22.70 pounds, making it distinctly more practical for field carry without vehicle support.
What does it weigh and what are the dimensions?
The rifle weighs 22.70 pounds with an overall length range of 34.40–43.10 inches depending on stock deployment. The folded configuration measures 34.40 inches for vehicle or case transport, extending to 43.10 inches when deployed for shooting, with a barrel length of 20.60 inches and receiver width of 2.75 inches. This places it between conventional .308 platforms and crew-served weapons in portability, requiring two-handed carry or a sling system for extended movement.
Who is this NOT for?
This rifle is not suitable for beginners, urban environments, or shooters without access to a 1,000+ yard range or NFA compliance resources. The 22.70-pound weight prohibits rapid maneuverability, and the .50 BMG ammunition costs approximately $5 per round compared to $1.20 for .308 Winchester, making sustained practice financially prohibitive for most recreational shooters. Additionally, the folding stock requires ATF Form 1 approval if configured as an SBR under 26 inches overall length, adding $200 and 9-month wait times to ownership.
What's in the box?
The package includes the rifle with pre-installed MX1 muzzle brake, one 5-round steel magazine, and a factory test target showing 0.75 MOA grouping at 100 yards. Documentation includes ATF compliance guidelines for interstate transport, a barrel threading specification sheet for suppressor compatibility, and a warranty registration card valid for 10 years against manufacturing defects. No optics, mounting hardware, or cleaning kits are included—expect to add $800-$2,000 for a suitable scope and Rings.
Is the CADEX CDX-50 Tremor worth it at $9,656.95?
At $9,656.95, the Tremor justifies its cost for specialized long-range shooters, military contractors, or accredited testing facilities requiring .50 BMG capability with transportability. The price includes the DLC-coated receiver, match-grade barrel, and folding stock system that would cost $12,000+ if custom-built, plus the regulatory compliance packaging saves ~40 hours of ATF research. For hunters or recreational shooters considering a Stevens 334 Rifle, the Tremor’s niche application and ammunition cost make it impractical despite its technical excellence.

Frequently asked questions
- Is it compatible with standard .50 BMG suppressors?
- Yes, it accepts any .50 caliber suppressor with 5/8-32 threading, though I recommend the SilencerCo Harvester Big Bore for its 12.5-inch length and 28-ounce weight. Plan for 4-6 months for ATF Form 4 approval before mounting.
- Does it fit in a Pelican 1750 case?
- Yes, in folded configuration at 34.40 inches, it fits diagonally in a Pelican 1750 interior (45.5 x 16 x 7.25 inches) with 2 inches of foam clearance. Remove the magazine to avoid pressure on the feed lips during transport.
- How long does shipping take?
- Expect 7-10 business days for processing and ground shipping due to FedEx and UPS .50 caliber firearm restrictions. Signature required upon delivery with adult ID verification—no exceptions for residential drop-off.
- Can I return it if it doesn't fit my needs?
- No, all firearm sales are final under Ironclad Armory’s policy due to federal serialization and transfer laws. I recommend renting a similar system like the Barrett M107A1 at a range for $150 per day before purchasing.
