IOSSO Blue Nyflex Bore Brushes


These ultra stiff synthetic bore brushes from Iosso are made with Iosso’s “Nyflex” fiber which is cobalt blue in color. The brush bristles are thicker and stiffer with more fiber per inch than other nylon brushes, brush core is brass, and they are designed to replace bronze bristle bore brushes. Most benchrest shooters use these brushes with Paste type cleaners like Iosso or JB. Eliminator brushes are expensive, but they hold up very well, don’t wear down or break down under heavy use so you don’t replace them very often. Sold singly.

Available in the following sizes:

  • 22 caliber
  • 6mm
  • 6.5mm
  • 7mm
  • 30 caliber
