Key Features
19-Inch Barrel with 3-Inch Chamber – Why it matters: The shorter barrel makes the MKX-3 easy to maneuver in tight spaces, and the 3” chamber lets you run magnum hunting loads or heavy defensive buckshot without a hitch.
Magazine-Fed AR-Style Platform – Why it matters: Reloads are fast—just drop a fresh magazine instead of fumbling with a tube. This design also gives you a familiar manual of arms if you already shoot AR-15s.
Adjustable Buttstock with Cheek Riser – Why it matters: You can dial in length of pull and comb height for a solid cheek weld, whether you’re shooting slugs or running a red dot.
Includes Backup Sights and Choke Kit – Why it matters: You get a functional sighting system out of the box, plus three chokes (cylinder, modified, full) to match your shot pattern to the target—clays, birds, or defense.
Uses Readily Available Turkish Magazines – Why it matters: Spare 5-round or 10-round mags are easy to source and affordable, so stocking up for range days or classes won’t break the bank.
Who It’s For
This shotgun fits shooters who want a low-cost, high-capacity semi-auto for home defense, range plinking, or 3-gun style drills. It also appeals to AR fans who want a shotgun that shares the same ergonomics—pistol grip, thumb safety, and magazine release. If you’re on a tight budget but still want a reliable 12-gauge that runs 3-inch shells, the MKX-3 is worth a hard look.
Pros & Cons
Pro: Price point under $400 makes it one of the most affordable magazine-fed shotguns on the market.
Pro: Lightweight at roughly 7.2 lbs—easy to carry and shoulder quickly.
Pro: Compatible with standard Turkish magazines, so spares are cheap and easy to find.
Con: Fit and finish are basic—expect some sharp edges and a gritty trigger pull that may need a break-in period or light polishing.

FAQ
What magazines does the SDS Radikal MKX-3 use?
It uses standard Turkish AR-style shotgun magazines, commonly available in 5-round and 10-round capacities. These are widely sold online and at gun shows. The included magazine holds 5 rounds.
Can I run 2.75-inch shells in this shotgun?
Yes. The MKX-3 has a 3-inch chamber, so it will cycle 2.75-inch and 3-inch shells reliably. Stick to high-brass or quality target loads for best function during break-in.
Is the stock adjustable for length of pull?
Yes, the buttstock has multiple positions and includes a cheek riser. You can collapse it for storage or extend it for a longer LOP.
Does it come with a choke tube set?
Yes, the package includes a choke kit with cylinder, modified, and full chokes. They thread into the barrel for quick swaps.
Is this shotgun reliable for home defense?
After a proper break-in (200–300 rounds), the MKX-3 runs reliably with quality ammunition. The manual of arms is simple, and the detachable magazine makes reloads fast. Just keep it clean and lubed.
