- 5R rifling is a type of rifling that uses five lands and grooves instead of the standard six or more1. The rifling system was introduced by Boots Obermeyer in the late 1980s1. The 5R system is five lands and grooves with 45 degree shoulders, which gives a better gas seal, more consistent velocity, longer barrel life, less friction and better accuracy2. The 5R system also reduces projectile deformation as it passes through the bore during the firing sequence, ensuring the projectile stays uniform instead of squeezing material into the grooves, which means better accuracy3.Learn more:✕This summary was generated using AI based on multiple online sources.
