Products of BBT Ltd (1)

Gunsmiths around the world need specialist tools such as quality chamber reamers and headspace gauges, and they need them quickly. Border Ballistics Technologies Ltd. (BBT) was created in 2015 to serve that need. The founder of the company, Geoffrey Kolbe, previously owned and ran the highly acclaimed rifle barrel manufacturer, Border Barrels Ltd., and over his 22 year association with the business Geoffrey Kolbe acquired a deep understanding of how to make chamber reamers perform well. Geoffrey Kolbe says that, “Customers expect the best workmanship from their gunsmith, so the gunsmith must use the best tools to satisfy his customers.”

The company is now ISO 9001 approved so you can be assured of the quality and accuracy of our reamers and gauges.

BBT make chamber reamers in carbide as well as high speed steel.. The company also makes headspace gauges other chamber gauges.  The company also makes counterbore reamers for crowning, and for cone bolt face or Remington bolt rebates. The company is now introducing rifling buttons and bore reamers for barrel makers

Although the factory is situated in a quiet rural valley in amongst sheep farms and forests of the Scottish Borders, the company ships gunsmithing tools around the world and makes a virtue of quick delivery. Even wild-cat reamers can be turned around within one week.

Reamers, gauges and other tooling can be purchased using pounds sterling, euros or US dollars. Standard chamber reamers are £165 (€210 or US$240). Headspace gauges are £40 (€51 or $58)
