Maxim Defense

What Maxim Defense does

Maxim Defense Industries is a privately held firearms and suppressor manufacturer founded in 2013 and headquartered in St. Cloud, Minnesota, operating from an ISO 9001:2015 certified facility. The company designs and builds a focused portfolio of AR-platform firearms organized around compact, suppressor-optimized configurations: the ultra-compact PDX (5.5" barrel with the patent-pending SCW stock system), the MDX CQB line, the integrally suppressed SDX and SDX RFLX series, and the MD:15, MD:9, MD:10, and MD:11 family covering 5.56 NATO, .300 BLK, 7.62x39, 9mm, .308 Win, 6.5 Creedmoor, and 8.6 BLK. Its differentiated intellectual property centers on M-Kore suppressor technology (fusing monocore low-back-pressure behavior with M-baffle sound suppression, user-serviceable with common tools), the SCW compact stock platform, the HATEBRAKE muzzle booster, and M-Kote bolt carrier finishes.

The business is a multi-channel hardware operation. Primary revenue comes from direct-to-consumer e-commerce on maximdefense.com, complemented by an authorized dealer network (with MAP pricing) and an international distributor inquiry system that requires State Department-authorized export processing. The company also monetizes a broader ecosystem of stocks and braces, bolt carrier groups, muzzle devices, TUI-branded ammunition, apparel, closeout items via "The Boneyard," and licensed 1:1 airsoft replicas manufactured by Vega Force Company. Customer segments span military and defense, federal/state/local law enforcement, and responsible civilian shooters, with product pricing ranging from roughly $145 accessories to $3,695 integrally suppressed SBRs. Financing is provided through Credova, and customer retention is supported by Patron and Patriot loyalty programs. President & CEO Michael Windfeldt leads the company, which currently employs 11-50 people.
