Abstract:
A method of modifying a firearm barrel comprising the steps of milling an existing barrel to create a sloped area with a larger diameter at a chamber end and a small action moving toward the muzzle end; placing an barrel nut on the barrel; placing a chamber bushing having a step with the step disposed at the chamber end; placing a brass pressing guide on the barrel and placing the barrel assemble with brass press guide and rear jacket tube in a press to press fit these components together; placing a gas block on the barrel adjacent to the rear jacket tube pressing the components tougher using the press; placing a front jacket tube on the barrel adjacent to the gas block and pressing the components tougher using the press; covering the threads of the barrel and placing a pour guide on the barrel; filling a void defined between the front jacket tube, rear jacket tube and barrel with a filler; placing a centering device on the barrel so that it is operatively associated with the front jacket tube to center the barrel in the front jacket tube while the filler is curing; placing a muzzle brake cap on the barrel and pressing the muzzle cap into the front jacket tube using the press; and, attacking a muzzle brake.
