Fast, Accurate Choke Tube Installations Using Reamers From Dave Manson
A quick and easy method to install choke tubes using a lathe (can be done by hand, however, a lathe gives superior results). Tap and reamer are precision ground from high speed steel and use the same interchangeable pilot bushings. Reamer has an enhanced end relief that provides a faster cut. Pilot bushings are available in diameter increments of .001", and are 2" long for accurate bore alignment. Factory instructions are included. Note: Read and understand the installation requirements before proceeding. For best results, remove any existing choke with the Angle Blade Expanding Choke Reamer prior to using the Loon Lake Choke reamer. Click here for proper installation requirements.
Use to thread barrels that are too thin to accept Win-Choke®-style tubes. The O.D. is .020" smaller than that required for Win-Choke tubes so they may be installed in proportionally thinner barrels.
