The Black Rain Ordnance Fusion runs a direct impingement gas system through a 16″ SOCOM profile 4150V chromoly barrel, a proven configuration for reliable function with the wide range of subsonic and supersonic loads available in .300 AAC Blackout. The salt bath nitride coated bolt carrier group resists corrosion and wear while reducing friction for smoother cycling shot after shot. A non-adjustable, low profile .750 gas block keeps the direct impingement system simple and reliable, and the forged Spec15 charging handle provides a solid, ergonomic grip for manipulating the action. This barrel and gas system combination is built to run hard with minimal maintenance.
The billet 7075-T6 upper and lower receiver set gives the Fusion a tight, precisely machined fit that improves overall rigidity compared to standard forged receivers. Finished in a distinctive Bronze Battleworn coating, the rifle stands out from typical black AR builds while the hardcoat anodized finish underneath protects the aluminum from the elements. The 12″ M-LOK slim handguard provides plenty of room for lights, foregrips, and other accessories without adding unnecessary bulk. MFT’s EPG16 grip and Minimalist stock round out the build with lightweight, ergonomic furniture, making this rifle available for sale at GrabAGun for shooters who want a distinctive, dependable .300 Blackout carbine.
