Quadradyn is a small, founder-run arms company in Pompano Beach, Florida. It exists because one cartridge family deserved a rifle designed around it rather than adapted to it.
01 // The founder
James, Quadradyn’s founder, has spent twenty years working with firearms. He has studied gunsmithing at Trinidad State College School of The American Rifle in addition to being a certified Cerakote applicator. James is on the shop floor every day ensuring quality comes first, and he responds to most customer service inquiries.
02 // The idea
In 2024 Quadradyn was envisioned as a business focused on the new ARC calibers from Hornady, the Advanced Rifle Cartridges, starting with 6mm ARC. The cartridge delivered long-range efficiency and low recoil from a compact platform. What it lacked was a rifle and a magazine designed for it from the start.
03 // The pivot
In early 2026 Quadradyn built and tested an AR-15 prototype in 6mm ARC. It worked, and it carried the compromise every AR-15 in 6 ARC carries: a modified magazine with no true double stack. When ICAR-magazine-compatible lower receivers were released to the public in mid-2026, Quadradyn set the prototype aside and rebuilt the rifle around the magazine the cartridge always needed. The result is the SARC-6.
With the SARC-6, Quadradyn became the first business to sell an ICAR-magazine-compatible AR to the public.

04 // What comes next
The rifle is the beginning. Quadradyn is branching into software, starting with Quadradyn Conquer, FFL management software with a planned free core release, and into anti-robotics defense, the field our Intelligence desk has been tracking as armed ground robots move from demonstration to deployment. As robotics overtake the modern battlefield and pose a threat to the homeland, Quadradyn intends to stand up a robotics division in the next 5 years with hopes of becoming a leader in robotic defense for Western militaries and the civilian defender.
