Radian Model 1 18" 6mm Arc Blk

The Radian Model 1 18" 6mm Arc Black is a semi-automatic rifle purpose-built for precision rifle competition, mid-range hunting, and dedicated marksmen seeking a modern platform in an emerging caliber. Chambered in 6mm Arc—a proprietary Hornady cartridge engineered for AR-15 platforms—this rifle combines Radian's proven engineering with the ballistic efficiency and low recoil impulse that make the 6mm Arc attractive for shooters who demand flat trajectories and reduced wind deflection without the ammunition scarcity issues that plagued larger magnums.

The 18-inch barrel is optimized for the 6mm Arc cartridge, balancing velocity and ergonomic length for field work and tactical applications. Topped with a Dead Air Flash Hider, the muzzle device minimizes flash signature and is compatible with suppressor mounting systems common in the AR ecosystem. The black Cerakote finish provides consistent corrosion resistance and durability across extended use cycles, whether in training, duty, or field environments. Total weight of 11.44 lbs positions this rifle as a handy, carbine-class platform without sacrificing sight radius or barrel length. The rifle ships with one 30-round magazine, standard capacity for modern 6mm Arc competition and hunting applications.

The Radian Model 1 in 6mm Arc appeals to precision rifle competitors evaluating non-traditional calibers for PRS or similar formats, hunters seeking a modern AR-platform alternative to traditional bolt-actions, and operators seeking a specialized platform for designated marksman roles. The 6mm Arc bridges the gap between 5.56mm NATO and larger cartridges, offering superior external ballistics with manageable recoil and higher first-round hit probability at extended ranges. This is not a mass-market rifle; it is purpose-driven for shooters who understand caliber selection and want platform flexibility without converting to an entirely different receiver or ergonomic system.
