.308 Ar 22'' Hybrid Rifle, Stainless

The .308 AR 22'' Hybrid Rifle, Stainless barrel by Criterion Barrels Inc is purpose-built for tactical shooters, competition marksmen, and law enforcement who demand precision in an intermediate-weight platform. Chambered in .308 Winchester, this 22-inch barrel delivers the ballistic performance and effective range required for duty applications, designated marksman roles, and long-range precision work. The stainless steel construction ensures superior corrosion resistance and thermal stability during sustained fire, making it ideal for operators who train in diverse environments or deploy in harsh conditions where barrel longevity is non-negotiable.

The hybrid contour design balances a heavy profile at the breech for rigidity and heat management with a tapered muzzle section for weight savings—the barrel weighs just 3.48 pounds, keeping the overall rifle profile manageable without sacrificing stiffness. Criterion's stainless steel construction resists fouling and erosion from repeated firing, extending service life significantly compared to chrome-moly alternatives. The 5/8-24 muzzle thread standard accommodates suppressor mounts, brakes, and compensators commonly used in tactical and precision applications, while the rifle-length gas system ensures reliable cycling across a range of ammunition loads and environmental conditions.

This barrel integrates seamlessly into any modern AR-10 or AR-.308 upper receiver assembly, making it an excellent upgrade for gunsmiths, armorer builds, or bolt-action alternative seekers. Installation requires standard AR platform assembly tools and basic gunsmithing knowledge; torque specifications and headspace verification are critical during setup. Operators working in designated marksman, precision rifle, or duty-rifle roles will recognize the hybrid profile as the sweet spot for accuracy, heat management, and handling characteristics across extended training cycles and operational deployments.
