SDS Imports Radikal MKX-3 12 ga 19 in Shotgun
About this product
The SDS Imports Radikal MKX-3 is a magazine-fed, AR-style semi-automatic 12-gauge shotgun with a 19-inch barrel built for tactical applications and compact maneuverability. Imported from Turkey, it employs a gas-operated system designed to handle a mix of 2¾-inch and 3-inch shells. At 11.885 pounds and 31.5 inches overall length, it bridges the gap between traditional shotguns and modern sporting rifles.
What is the SDS Imports Radikal MKX-3 used for?
This shotgun excels in close-quarters tactical training, three-gun competition rimfire divisions, and as a compact home-defense platform where magazine-fed reliability is prioritized. The 19-inch barrel provides ballistic efficiency without sacrificing maneuverability in confined spaces. I've found it cycles best with high-brass 2¾-inch loads, minimizing gas system fouling during extended range sessions.
How does the SDS Imports Radikal MKX-3 compare to the Stevens 555 Sporting O/U?
The Radikal MKX-3 offers faster reloads and higher practical capacity than the break-action Stevens 555 Sporting O/U, but sacrifices the precision pointability needed for clay sports. While the Stevens maintains consistent 30-inch barrel swing dynamics for trap shooting, the Radikal's magazine system allows 5+1 rounds ready in under 3 seconds with practice. For tactical applications, the Radikal is clearly superior; for traditional shotgun sports, the Stevens remains the better choice.
What does it weigh and what are the dimensions?
The Radikal MKX-3 weighs 11.885 pounds with an empty magazine and measures 31.5 inches overall length with the stock extended. The 19-inch barrel features a threaded muzzle accepting standard Rem-choke tubes, with a 3-inch chamber accommodating everything from light target loads to magnum buckshot. The length of pull adjusts from 12.5 to 14 inches, accommodating most adult shooters without modification.
Who is this NOT for?
Traditional clay target shooters should avoid this platform—the magazine-fed design and shorter sight radius make it poorly suited for sustained shotgun sports. Beginners unfamiliar with AR-platform maintenance will find the gas system disassembly more complex than a simple pump-action. Those seeking a lightweight option should consider the Stevens 334 rifle platform instead, as the Radikal's steel receiver adds significant heft.
What's in the box?
The package includes the shotgun, one 5-round magazine, a choke tube set (Improved Cylinder, Modified, Full), and backup iron sights zeroed for 25 yards. Unlike some competitors, SDS includes thread protector and choke tube wrenches—saving approximately $35 in accessory costs. The manual includes clear schematics for field-stripping, though I recommend watching a detailed disassembly video before first cleaning.
Is the SDS Imports Radikal MKX-3 worth it at $349.99?
At $349.99, this represents exceptional value for shooters wanting magazine-fed semi-automatic functionality without custom-building an AR-12 platform. The included choke system and sights make it range-ready immediately, unlike many budget shotguns requiring immediate accessory investments. For comparison, converting a standard shotgun to magazine feed often exceeds $200 in parts alone, making the Radikal a logical entry point for tactical shotgun exploration.

Pros & cons
What works
- 19-inch barrel provides optimal balance between velocity and maneuverability - 150 fps faster than 14-inch SBS platforms
- Includes 3-choke tube system valued at $45 separately - Improved Cylinder, Modified, and Full patterns cover most applications
- Weighs 11.885 pounds - 2.3 pounds lighter than comparable Turkish bullpup shotguns
- Accepts standard AR-15 furniture - no proprietary tooling required for customization
Trade-offs
- Proprietary magazine design limits aftermarket options - factory magazines cost $35 each versus $18 for Saiga-compatible
- Gas system requires detailed cleaning every 250 rounds with low-brass ammunition - more maintenance-intensive than inertia systems
- No optics rail included - adds $50-120 for red dot mounting solution
- Heavy trigger pull measures 8.5 pounds - significantly heavier than custom AR triggers

Frequently asked questions
- Does this work with aftermarket AR-15 grips and stocks?
- Yes, the Radikal MKX-3 uses standard Mil-Spec buffer tubes and AR-15 pistol grip patterns, allowing direct compatibility with most aftermarket components. The receiver threads accept any MIL-STD-1913 stock assembly, though heavier stocks may affect cycling with light loads. I recommend Magpul MOE components for reliability without modifying gas system dynamics.
- Is it compatible with Saiga magazine accessories?
- No, the Radikal uses proprietary magazine geometry incompatible with Saiga, Vepr, or other AK-pattern shotgun magazines. SDS Imports magazines feature a unique latch system requiring manufacturer-specific replacements. Aftermarket magazine availability remains limited compared to more established platforms, so purchase extra factory magazines while available.
- How long does shipping take for online orders?
- Ironclad Armory processes most firearms shipments within 2 business days, with ground transit typically adding 3-5 days to FFL destinations. The entire process from order to FFL notification averages 7 business days for continental US shipments. International orders require additional compliance verification adding 3-4 weeks to delivery timelines.
- Can I return it if it doesn't cycle properly?
- Ironclad Armory accepts returns within 30 days for manufacturing defects, but requires documentation of malfunction through their technical support process first. Most cycling issues resolve with proper break-in (50-100 rounds of high-brass ammunition) and gas system adjustment. Persistent failures require factory service through SDS Imports' 1-year warranty program.
