Noveske x Irregular Defense 6mm ARC SBR 12.5" SS Barrel - 20 Rd

The Noveske 12.5 inch 6mm ARC Rifle is a premium, purpose-built platform engineered for shooters who demand precision accuracy, durability, and elite-level components. Chambered in 6mm ARC, this rifle delivers exceptional ballistic performance with superior consistency—ideal for both long-range precision and tactical applications.

At the core is a 12.5” 416R stainless steel barrel with a 1:7 twist rate, individually serialized for quality control and finished with a hand-polished Noveske Match Chamber. Combined with a mid-length gas system, this setup ensures smooth cycling, enhanced reliability, and outstanding accuracy. The barrel is paired with an Irregular Design HESYCHIA hybrid flash hider, reducing muzzle signature while maintaining performance.
