The 10.5 inch HBAR profile barrel is chambered in 338 ARC with a 1 in 8 twist rate for projectile stabilization. The pistol gas system is matched to the barrel length for reliable cycling. The micro low profile gas block sits under the handguard for a clean profile. The GI birdcage flash hider provides standard muzzle device function.
