From Being Bold to Bolt: Fluted (Spiral) Bolt – 6x Flutes

Our precision-engineered fluted spiral bolts feature six helical flutes that combine performance, reliability, and style:

  • Weight Reduction – Material is removed without compromising strength, resulting in a lighter, more responsive bolt.
  • Debris Clearance – Spiral grooves actively channel dirt, sand, and unburned powder away for cleaner, more reliable cycling.
  • Heat Dissipation – Increased surface area improves cooling efficiency, even during sustained firing sessions.
  • Smoother Cycling – Reduced bearing surface contact lowers friction, delivering an effortless, refined bolt throw.

Engineered for both function and aesthetics, the six-flute spiral design enhances performance and gives your custom rifle a striking, professional look.
