The Harris MARS: Centurion Arms’ Flagship
The Harris MARS (Mini Assault Rifle System) is Centurion Arms’ most distinctive product — an 11-inch barrel PDW-style rifle chambered in the proprietary 5.56×30mm cartridge, achieving approximately 2,600 ft/s muzzle velocity from a package just 25 inches overall. The MARS uses a short-stroke piston system for low recoil and high reliability in a compact platform, and retains the AR-15’s familiar manual of arms despite its substantially shortened action geometry. For operators and enthusiasts who need a rifle that bridges the gap between a submachine gun and a carbine, the MARS is in a category of its own.
Centurion Arms AR-15 Rifles
Beyond the MARS, Centurion Arms produces premium AR-15 rifles built to tight tolerances with quality components throughout. Their AR-15 lineup focuses on reliability and accuracy for serious shooters who want a step up from standard production AR-15s without moving to fully custom builds. Centurion Arms rifles use mil-spec geometry with premium barrel and component sourcing, positioned between standard production ARs and fully custom builds.
