HBAR Rifle-length AR15 Barrels

Criterion’s rifle-length HBAR AR15 Barrel is a heavy-weight contour that handles high heat and absorbs recoil more effectively. Its heavy frame provides increased rigidity, which allows for consistent precision. These barrels are commonly used in precision gas-gun builds and competition rifles.

Why HBAR?

• Heavy contour - increased rigidity; handles high heat and absorbs recoil more effectively
• .223 Wylde chamber - safely and reliably fires both .223 Remington and 5.56 NATO with improved accuracy due to more consistent chamber pressures
• Chrome-lined - improved barrel life and corrosion resistance without degrading accuracy
• 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
• 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.
