Heavy Hybrid 22” 308 Barrel

Criterion’s 22” 308 Heavy Hybrid Barrel is a heavy-weight government contour barrel for large frame DPMS pattern rifles. The heavy weight increases stability, consistency, and rigidity over conventional designs.

Why 308 Heavy Hybrid?

• Heavy contour - superior heat absorption, stability, and rigidity
• 308 Win M118 LR Match chamber - compatible with both 7.62x51 NATO and .308 Win ammunition; optimized for heavier, longer bullets
• Stainless Steel - natural corrosion resistant and improved barrel break-in
• Honed - refines bore for superior uniformity to reduce bullet deformation
• Hand-lapped - essential for accuracy and to minimize fouling
• Polished chamber - reliable extraction and feeding
• Rifle gas system - optimized gas port for suppressed and unsuppressed use
• .875 gas journal - easy and secure installation
• 5/8x24 muzzle threads - compatible with most muzzle devices and suppressors
• Precision-machined barrel extension - safe and reliable feeding

Why Headspace Matters

Purchasing a headspaced bolt is not required. However, Criterion's headspace service guarantees optimal bolt to barrel fitment using premeasured bolts and certified headspace gauges, helping to maximize the performance and function of your build.

Headspace (the critical measurement from the bolt face to the shoulder of the chamber), must be checked for optimal performance and reliability. Proper headspace produces consistent chamber pressures and seating depths which results in increased accuracy and reliability, while reducing wear and tear on internal parts and components.
