Do Contours Affect Barrel Weight?
Yes, the contour of a barrel affects its weight. Heavier contours help resist barrel movement and wandering as it heats up during shooting.
Does Contour Affect Shooting Performance?
Yes, while heavier barrels may offer better stability and reduced fatigue, lighter contours can perform just as well in some cases.
Should Suppressors be Used on Any Barrel Contour?
No, suppressors are typically more effective on heavier barrels, influencing harmonic vibrations positively. We recommend medium palma contours or larger for suppressor attachment.
Why is Single Point Cut Rifling Superior?
Single point cut rifling, unlike button rifling, eliminates stress on the barrel blank, ensuring consistent performance without bore size issues or thread-related problems at the muzzle.
Importance of Barrel Fluting
Fluting reduces barrel weight, improves cooling efficiency, and adds aesthetic appeal. However, excessive fluting can cause harmonic issues affecting accuracy.
Why is Rifling Style Important?
While different rifling styles exist, our 5R rifling stands out for its ability to enhance bullet flight and resist bullet failure, especially noticeable with specific bullet types.
