US12624915 - Suppression device with purposely induced porosity for firearm

The patent describes a suppression device for firearms that features a body and a core with a baffle, designed to manage sound and pressure through controlled porosity. The porosity is intentionally structured, with the core’s porosity being greater than that of the body, enhancing the device’s effectiveness.

Claim 1

1 . A suppression device comprising: a body including an outermost external surface of the suppression device, a first end, and a second end; a core configured to be inserted into the body and including a baffle; and a bore extending completely through and along a longitudinal axis of the suppression device, wherein porosity is a fraction of a volume of pores per volume of mass in a material of the suppression device, a structure of the pores is not random, and the porosity of a portion of the core including the baffle is greater than the porosity of a portion of the body. a body including an outermost external surface of the suppression device, a first end, and a second end; a core configured to be inserted into the body and including a baffle; and a bore extending completely through and along a longitudinal axis of the suppression device, wherein porosity is a fraction of a volume of pores per volume of mass in a material of the suppression device, a structure of the pores is not random, and the porosity of a portion of the core including the baffle is greater than the porosity of a portion of the body.
