Abstract
A monolithic barrel for a weapon has an integral suppressor. The barrel and integral suppressor can be machined from a single piece of material, which can eliminate the need to attach separate components to the barrel. The monolithic barrel has a barrel bore for firing a projectile that produces discharge gas. To suppress the discharge, the barrel defines one or more baffles separating expansion chambers toward a distal end of the barrel. The barrel further defines one or more channels along the length of the barrel that provide extend flow paths for the discharge gas from the barrel's bore. Greater reductions in sound can be achieved relative to the overall barrel length due to the integral suppressor.
Claims14
A method of making a gun barrel comprising an integrated suppressor, the method comprising:
- providing a barrel blank comprising:
- a breach end,
- a muzzle end,
- a long axis,
- an exterior surface, and
- a bore extending through the barrel blank along the long axis from the breach end to the muzzle end and having a first diameter,
- forming a suppressor section and a barrel section in the barrel blank, wherein the suppressor section extends from the muzzle end to a first location along the barrel blank and the barrel section extends from the first location to the breach end, wherein forming the suppressor section and a barrel section comprises:
- reaming the bore within the suppressor section so that the bore within the suppressor section has a second diameter that is greater than the first diameter, and
- machining a plurality chambers within the suppressor section, wherein the chambers extend through the barrel blank perpendicular to the long axis, thereby forming baffles in the barrel blank.
