Description

Criterion’s Hybrid contour is a mid-weight barrel that offers a perfect balance between weight and intelligently distributed barrel material for excellent heat absorption and consistent harmonics. This barrel can be easily carried in the field all day but will also provide exceptional performance even under extreme use and high rates of fire.

Headspace (the bolt to barrel fitment), 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.  Add a headspace bolt to your order, and we will pair a bolt to your barrel for optimal performance.
