The Black Rain Ordnance BR Cardiac 6mm ARC 18 FDE is a purpose-built semi-automatic hunting rifle that blends precision engineering with a rugged field-ready configuration. Built on the Spec 15 forged aluminum receiver set and paired with an 18" 4150V chromoly barrel, this rifle is designed to deliver consistent accuracy shot after shot. A BRO round compensator, 17.76" M-LOK slim handguard, and Magpul MOE grip with ACS-L stock round out a package focused on control, balance, and shooter comfort.

Chambered in 6mm ARC, the BR Cardiac offers flat trajectories and excellent downrange performance, making it well suited for medium-game hunting and extended-range target work. The direct impingement gas system with a .750 low profile non-adjustable gas block, combined with a salt bath nitride coated Spec 15 BCG and crisp single-stage trigger, supports reliable cycling and predictable trigger breaks. Whether you are refining skills at the range or preparing for a demanding hunt, this rifle reflects Black Rain Ordnance’s reputation for careful craftsmanship and dependable performance.
