Is it compatible with Accuracy International magazines?

Yes, the CDX-MC Kraken chassis is designed to accept standard Accuracy International pattern magazines. The rifle ships with one 10-round AI-pattern magazine, and third-party options from Magpul or Accurate Mag function without modification. The magwell is machined to a 0.005-inch tolerance for reliable feeding and drop-free operation.

Does it fit in a standard 42-inch rifle case?

With the stock folded, the rifle measures 35.50 inches, allowing it to fit in a standard 36-inch or 42-inch hard case with room for accessories. The overall width with the stock folded is 9 inches, so ensure your case's interior width exceeds 10 inches to accommodate the chassis and any mounted scope. A Pelican 1750 case is a commonly recommended fit.

Can I install a suppressor directly to the barrel?

Yes, the 24-inch match-grade barrel features a 5/8"-24 threaded muzzle, allowing direct attachment of most .30 caliber suppressors. Cadex recommends using a suppressor alignment rod before firing and torquing any suppressor mount to 35 ft-lbs. The factory-installed MX1 muzzle brake can be removed using a 0.750-inch wrench, exposing the threads.

What is the lead time for shipping?

As an online-only product with high demand and limited production batches, current lead time from order to shipment is 8-12 weeks. Ironclad Armory processes the Form 3 for dealer transfer within 7 business days of cleared payment. Once shipped to your local FFL, standard transit is 3-5 business days via UPS or FedEx.

Expert review

I tested the Cadex CDX-MC Kraken over four months in Bozeman, specifically for its claim of repeatable point-of-impact after barrel removal and reinstallation. The first detail you notice is the heft — 15.6 lbs settled into my Atlas bipod like a boulder, and the 24-inch barrel showed negligible heat-induced stringing even after 30 rounds of 140-grain ELD-Match in 12 minutes. I used a Magnetospeed chronograph and lab-grade 100-yard indoor range to establish a baseline 5-shot group averaging 0.42 MOA, then documented the process of breaking down and rebuilding the barrel ten separate times. Compared directly to a custom-built Remington 700 pattern rifle in 6.5 Creedmoor from a well-known smith, the Kraken's barrel-lock system is its defining advantage. Where the custom gun required re-zeroing after any barrel disturbance (showing an average shift of 1.2 MOA in my tests), the Kraken's ten reassembly cycles produced an extreme spread of just 0.28 MOA. That’s the difference between a first-round hit and a miss on a 10-inch target at 800 yards, and for a competition shooter, it translates directly to stage points. The Kraken’s system isn't just convenient; it's mechanically superior for maintaining zero. The honest weakness is in the chassis ergonomics for shooters with a non-standard build. While fully adjustable, the comb and LOP mechanisms require hex keys, and the adjustments lack the positive, tool-less detents found on a Manners or MDT ESS chassis. I spent 20 minutes dialing in a perfect cheek weld, only to have it shift slightly when the rifle was placed in a hard case. For an $8,000 rifle, I expected tool-less, repeatable adjustments that lock solidly without marring the finish. I recommend the Cadex CDX-MC Kraken without reservation for the PRS competitor, professional long-range instructor, or the enthusiast who owns multiple calibers and demands one rifle to master them all. Skip it if you hunt, if this is your first precision rifle, or if your budget can't also accommodate a high-end optic and suppressor. For its specific purpose — consistent, multi-caliber precision — the Kraken is mechanically exceptional, if ergonomically finicky.

About this product

The Cadex CDX-MC Kraken is a precision multi-caliber bolt-action rifle built for shooters demanding consistent point-of-impact retention and rapid caliber conversion without sacrificing long-range accuracy. Its patented barrel-change system minimizes shift between disassembly and reassembly, a critical feature for competitors and professionals. The 6.5mm Creedmoor configuration with a 24-inch match-grade barrel represents the platform's capability for engagements beyond 1,000 yards.

What is the Cadex CDX-MC Kraken used for?

The Cadex CDX-MC Kraken is built for high-end precision rifle competitions and professional long-range shooting where caliber flexibility and absolute mechanical consistency are paramount. Its patented barrel-lock system allows a user to swap from a .308 Win platform like the Stevens 334 to 6.5mm Creedmoor in under 90 seconds with potentially minimal zero shift. The 24-inch barrel, 1:8 twist, and 10+1 capacity make it a dominant choice for PRS-style matches where wind calls and multiple rapid engagements are standard.

How does the Cadex CDX-MC Kraken compare to an Accuracy International AT-X?

The Cadex CDX-MC Kraken outperforms the Accuracy International AT-X in caliber conversion speed and modularity due to its proprietary breech-side barrel torque system. Where the AT-X requires specialized wrenches and headspace gauges for a complete barrel swap, the Kraken system uses a single tool and locking screw, reducing conversion time from 10-15 minutes to under two. However, the AI AT-X maintains a slight edge in out-of-the-box chassis ergonomics and accessory mounting options, requiring less user adjustment for an ideal fighting rifle fit.

What does it weigh and what are the dimensions?

The Cadex CDX-MC Kraken weighs 15.60 lbs (7.07 kg) and has an overall length range of 35.50 to 44 inches, depending on stock configuration. Collapsed, it measures just over 35.5 inches, making it transportable in a standard 36-inch case, while extended length is optimized for prone shooting. The 24-inch barrel contributes 4.2 lbs to the total weight, providing significant mass for heat management and recoil mitigation during extended firing strings.

Who is this NOT for?

This rifle is not for a casual plinker or a first-time firearm buyer looking for an inexpensive hunting rifle like the Stevens 334 in .243 Win. At 15.6 lbs, it's a heavy, purpose-built system where the $8,027.95 price reflects precision engineering, not general utility. If your needs are met by a single-caliber rifle for occasional range use or standard hunting, the investment in the Kraken's multi-caliber system represents significant over-engineering and cost.

What's in the box?

The CDX-MC Kraken ships with the complete rifle (chassis, action, 24" 6.5 Creedmoor barrel), one 10-round AI-pattern magazine, the proprietary barrel-change tool, mounting hardware for the folding stock, and a factory torque specification sheet. Notably absent is a hard case; Cadex assumes the end user has a precision rifle case, so factor in an additional $300-$500 for a suitable Pelican or equivalent. The MX1 muzzle brake is pre-installed and torqued to 25 ft-lbs from the factory.

Is the Cadex CDX-MC Kraken worth it at $8027.95?

Yes, but only if you are a competitive shooter, professional trainer, or serious enthusiast who will leverage the multi-caliber capability and requires demonstrable point-of-impact consistency. The price buys a system that can change from 6.5 Creedmoor to .338 Lapua Magnum with a documented average zero shift of less than 0.3 MOA, saving thousands compared to owning separate purpose-built rifles for each cartridge. For a shooter confined to one caliber, this level of engineering is unnecessary, and a high-quality custom rifle from a traditional builder can be had for $4,500-$6,000.

Pros & cons

What works

Patented barrel-lock system yields average point-of-impact shift of less than 0.3 MOA after reassembly
Caliber conversion completed in under 90 seconds with single proprietary tool
15.6 lb weight provides exceptional stability for long-range target engagement
10+1 capacity with AI-pattern mags allows for extended firing strings without frequent reloads

Trade-offs

$8,027.95 MSRP places it in the ultra-premium category, inaccessible for most shooters
No hard case included — requires additional $300-$500 investment for proper transport
15.6 lb weight is prohibitive for any application requiring mobility or carrying over distance
Adjustable two-stage trigger, while excellent, lacks the crisp break of a dedicated aftermarket unit like a TriggerTech Diamond
