This barrel adapter was designed for the gunsmith with smaller lathes in mind. If your chambering method is to mount the barrel through the spindle bore, and indicate the chamber end at the chuck, and the muzzle out the rear of the spindle with a spider.THIS is just what your looking for. The BTS mounts on the last 1.250 inches of the muzzle end of the barrel and works on barrels from 1/4 " to 1.3". Also .17 through .50 cal. with no parts interchange. The time to install is about 15 SECONDS! This unit just WORKS! And IT DOESN'T LEAK!
