The right barrel is crucial for multiple factors, including accuracy, velocity, and consistency of your shots. It needs to be able to maintain its precision under heat, withstand repeated shots, and have the right twist rate to ensure the maximum velocity of your bullets.
Stainless Steel or Carbon Fiber are the recommended choices. With Stainless Steel, you will get a more durable barrel. Carbon fiber helps reduce weight while maintaining rigidity and strength.
Pre-fit and Pre-chambered are threaded for specific actions or rifle models and will typically have correct headspacing. Because the pre-fit barrels are designed for specific footprints, they can be quickly and easily installed into your chassis.
A medium or heavy profile, like the MTU or Heavy Palma, provides better heat dissipation and stability for repeated shots. Lighter profiles, such as the Sendero, reduce the weight of your weapon but may cause it to heat up faster, which can impact accuracy.
Both fluted and carbon fiber barrels are excellent choices for weight reduction, while maintaining rigidity and making the weapon easier to maneuver during a dynamic PRS stage. While both types are lighter in weight, carbon fiber takes that a step further compared to a fluted barrel, offering an additional weight reduction due to the material used in the barrel's construction.
