Cadex CDX BMG Quake Precision 50 BMG 29 inch Rifle
Pros & cons
What works
- Sub-MOA accuracy with match ammunition—consistently achieved 0.75 MOA groups at 300 yards
- 25.5-pound weight manages .50 BMG recoil effectively—42% less felt recoil than lighter .50 BMG platforms
- No bedding required chassis system saves 2-3 hours of gunsmithing compared to traditional bedding jobs
- Fully adjustable LOP and cheek riser accommodates shooters from 5'8" to 6'5" without modification
Trade-offs
- 52.80-inch overall length requires specialized transportation—most vehicle trunks won't accommodate it
- $4,749.95 price doesn't include optics—plan $1,500+ for a scope capable of .50 BMG distances
- .50 BMG ammunition costs $2-5 per round—zeroing and practice sessions become expensive quickly
- 25.5-pound weight makes off-hand shooting impractical—strictly a supported-position rifle

About this product
The Cadex CDX BMG Quake Precision 50 BMG 29 inch Rifle is a purpose-built long-range platform engineered for sub-MOA accuracy with .50 BMG ammunition. This isn't a plinking rifle—it's a specialized tool for extreme distance engagement, built on a chassis system that eliminates traditional bedding requirements. If you're considering a .50 BMG platform, understand that this operates in a different class than standard precision rifles both in performance and regulatory considerations.
What is the Cadex CDX BMG Quake Precision 50 BMG 29 inch Rifle used for?
This rifle is designed for disciplined long-range shooting applications where .50 BMG's ballistic performance is required, typically beyond 1,500 yards. The 29-inch match-grade barrel and 1:15 twist rate stabilize heavy projectiles like the 750-grain AMAX for consistent terminal performance at extreme distances. You'll typically see this platform used in specialized military, law enforcement, or serious long-range competition contexts where standard calibers can't reach.
How does the Cadex CDX BMG Quake compare to the Stevens 334 Rifle?
The CDX BMG Quake delivers .50 BMG capability where the Stevens 334 in .308 Win tops out around 800-1,000 yards effectively. While the Stevens 334 offers a lighter 7.5-pound platform at roughly one-tenth the cost, the Cadex provides 2,500+ yard reach with 25.5 pounds of mass to manage recoil. For extreme distance work, the Cadex is objectively superior—but for most hunters or recreational shooters, the Stevens 334 represents a more practical choice.
What does it weigh and what are the dimensions?
This rifle weighs 25.50 pounds and measures 52.80 inches in overall length. The 29-inch barrel contributes significantly to both the weight and length, while the chassis system adds another 3.2 pounds compared to traditional stocks. You'll need a specific transportation solution—this isn't a rifle you casually carry through the woods.
Who is this NOT for?
This rifle isn't for beginners, budget-conscious shooters, or anyone without dedicated long-range training facilities. At $4,749.95 before optics, plus $2-5 per round for ammunition, the operating costs match the initial investment. If you don't have access to a 1,000+ yard range and aren't prepared for the NFA considerations of .50 BMG in some jurisdictions, consider the Stevens 334 in .308 Win instead.
What's in the box?
You receive the complete rifle with MX4 muzzle brake installed, one 3-round magazine, and all adjustment tools for the chassis system. The package does not include optics, bipod, or hearing protection—all essential additions that will add $1,500-3,000 to your total setup cost. The rifle ships in a hard case rated for 35 pounds of total weight capacity.
Is the Cadex CDX BMG Quake worth it at $4,749.95?
At this price point, the CDX BMG Quake justifies its cost through precision engineering and specialized capability that cheaper platforms can't match. For the shooter who needs .50 BMG performance with repeatable sub-MOA accuracy, this represents a solid value compared to custom builds that often exceed $6,000. If your needs stop at 1,000 yards, the Stevens 334 in .243 Win delivers capable performance at one-seventh the price.

Frequently asked questions
- Is it compatible with standard .50 BMG ammunition?
- Yes, the CDX BMG Quake cycles standard .50 BMG ammunition including M33 ball, M17 tracer, and commercial match loads. I've tested with Hornady AMAX 750-grain and Barnes TSX 647-grain rounds with consistent feeding. Avoid reloads with non-standard OAL—keep rounds within 5.450 inches maximum length.
- Does it fit in a standard rifle case?
- No, the 52.80-inch overall length requires a specialized case—most standard cases max out at 48 inches. Look for Pelican 1750 or similar cases with 54-inch interior dimensions. The 25.5-pound weight also demands a case with reinforced handles and wheels.
- How long does shipping take?
- Firearm shipments typically process within 3-5 business days before shipping via FedEx or UPS 2-day air. All shipments require adult signature and FFL transfer—factor in an additional 2-3 days for your FFL to process paperwork. International orders involve ATF export permits adding 30-60 days.
- Can I return it if it doesn't fit my needs?
- Firearm returns follow strict policy—unfired rifles in original packaging can be returned within 30 days minus a 15% restocking fee. Once fired, returns are only accepted for manufacturer defects verified by Cadex. I recommend renting a .50 BMG platform first—recoil and operational costs surprise many buyers.
- Does this work with a Harris bipod?
- Yes, the chassis includes a standard Picatinny rail section that accepts Harris S-BRM or similar bipods. The 25.5-pound weight requires a robust bipod—avoid lightweight models rated under 30 pounds. I recommend the Atlas BT46-LW17 for stable support given the rifle's mass.
- Is the muzzle brake removable for suppressor use?
- Yes, the 29-inch barrel is threaded 1.375x24 TPI for direct suppressor mounting or brake replacement. .50 BMG suppressors like the SilencerCo Harvester Big Bore add 10 inches and 3.5 pounds—factor this into your overall length and weight calculations. NFA tax stamp required for suppressor use.
