Maxim Defense

Maxim Defense

Maxim Defense, founded in 2014 and headquartered in St. Cloud, Minnesota, has rapidly evolved from an AR-15 stock specialist into a global developer of advanced firearms, suppressors, and related accessories. Initially gaining recognition at SHOT Show 2016 with its universal CQB-style stocks and stabilization braces, the company launched its first firearm platform, the PDX personal defense weapon, in 2019 — ultimately earning “Best of SHOT” honors from Recoil magazine. Maxim Defense’s signature PDX-SBR packs a 5.5‑inch barrel into a compact 18.75″ platform, built with military-grade materials like titanium, stainless steel, and high-grade aluminum. Patented features include the SCW stock system, HATEBRAKE muzzle booster, and modular M-RAX/M-Slot handguards — delivering exceptional ergonomics and performance in tight environments. The PDX:SD variant integrates a suppressor‑tuned DSX model featuring Maxim’s proprietary M-Kore technology, reducing gas blowback and noise while maintaining reliability. Beyond PDWs, Maxim Defense now offers a full product suite—including MD-series rifles (MD:9, MD:10L, MD:11, MD:15L), MDX, and SDX platforms—alongside stocks, suppressors, buffer systems, muzzle devices, and ammo accessories. The company’s suppressor lineup, especially the lightweight PRS model and MSX/MS-series, is gaining rapid popularity among hunters and tactical professionals. Committed to R&D, Maxim focuses on delivering purpose-built tools for military, law enforcement, and civilian markets—balancing innovation, industrial design, and field-tested durability.

The DS Series is closely related to the DSX. Tough as hell, extremely quiet, and quite possibly the most enjoyable shooting experience you’ve had thanks to the M-Kore Technology. The DS is what we recommend when you’re not running anything below a 10.3” barrel, no matter what torture you put it through. Plus, it’s rated for full-auto shooting. The main differences from the DSX are the absence of the secondary tube retention ring and the use of Grade 9 titanium on the tube instead of Grade 5. Grade 5 titanium is much more expensive, and it simply isn’t needed in the DS series.
