RISE Armament Upper Receiver Complete 6mm ARC 18" Threaded Grey

Rise Armament Upper Receiver Complete Upper Features The Rise Armament Upper Receiver centers on an 18 inch 416R stainless steel barrel a material chosen by precision rifle builders for its combination of accuracy potential and corrosion resistance. Chambered in 6mm ARC the barrel is cut with a 1:7 twist rate to stabilize the longer heavier bullets that make the cartridge effective at extended ranges. The barrel is threaded 1/2x28 at the muzzle giving shooters the option to add a muzzle brake or suppressor for recoil management or reduced sound signature. A black Cerakote finish on the barrel protects it from the elements while contrasting against the grey aluminum receiver for a distinctive look. Built on an aluminum receiver the upper keeps weight manageable while maintaining the strength needed for repeated firing of a long-range cartridge like 6mm ARC. As a complete upper it is ready to install onto a compatible AR-15 lower giving builders a straightforward path to a 6mm ARC precision rifle without machining or fitting a barrel themselves. The combination of an accurate barrel a stabilizing twist rate and a threaded muzzle makes this upper well suited to long-range target shooting and hunting applications. For AR-15 owners looking to add a dedicated 6mm ARC precision upper to their collection the Rise Armament Upper Receiver delivers accuracy-focused components in a ready-to-install package.
