our history

Dave Manson founded Manson Precision Reamers in 1998. Under his leadership, engineering prowess, and industry expertise, the company grew to become the country’s premier supplier of chamber reamers, headspace gauges, and cutting tools for firearms. Retiring in 2022, Dave continues to be an active and valued consultant for the company.

our mission

From the first day we opened shop until today, we’ve dedicated ourselves to providing our clients with the finest and most precise cutting tools and gauges available. Whether you’re a large manufacturer, one-man shop, or hobbyist, you’ll find our dedication to providing you with the proper tooling is unsurpassed.

our future

Under the leadership of President Jeff Blevins we’re increasing our already large stock of standard chambering reamers and headspace gauges for all types of firearms with the goal to offer any caliber and/or wildcat on special order.

We’ll also continue to expand our selection of tooling for other gunsmithing tasks. From action truing to muzzle re-crowning, from installation of screw-in chokes to extending forcing cones and gauging barrel wall thickness, it’s likely we have a product that will help in your work.
