Here is a summary of U.S. Patent No. 12,018,906.

Patent Information

• Title: Firearm suppression system
• Assignee: Jarvis Arms LLC
• Inventor: Lonnie Jarvis
• Filing Date: October 23, 2023
• Issue Date: June 25, 2024
• Abstract: A firearm suppression system includes a housing, a muzzle adapter, an end cap, and a core. The housing includes a first aperture at a first end and a second aperture at a second end. An inner compartment may be interposed between the first aperture and the second aperture. The inner compartment may be configured to receive the core. The muzzle adapter may be threadably coupled near the first end of the housing, and the end cap may be threadably coupled to the second end of the housing. The core may be removably attachable to the housing and positioned within the inner compartment of the housing. Between an outer surface of the core and the inner surface of the housing may be a channel that equalizes pressure. The outer surface of the core may comprise a plurality of apertures that lead to baffles.

Plain-Language Overview of Independent Claims

This patent contains three independent claims, each describing a different embodiment of the firearm suppression system.

• Claim 1: This claim describes a firearm suppressor with a main housing and a removable internal "core." A key feature is a channel that runs the full length of the suppressor, located between the outer surface of the core and the inner surface of the housing. This channel is designed to "equalize pressure." The core has multiple openings on its surface that allow hot gases from a fired cartridge to escape from the central path of the bullet into this outer channel. The goal is to manage the gas pressure to reduce sound, recoil, and the amount of gas blowing back at the shooter.

• Claim 13: This claim focuses on an "end cap" that is "actuated by pressure." When a bullet is fired, the gas pressure activates a "closure member" within the end cap. This member moves to partially obstruct the exit hole for the bullet (the projectile aperture) after the bullet has passed. This mechanism is intended to trap the gases inside the suppressor for a longer duration, thereby further reducing the sound of the gunshot. The suppressor still contains a housing and a core with baffles and apertures to manage gas flow internally.

• Claim 17: This claim describes a more complex version of the suppressor system. It includes the standard housing, core, and end cap, but adds two specific features. First, it incorporates "pressure reduction tubes" that pass through several of the internal baffles. These tubes are designed to redirect high-pressure gas from near the muzzle back towards the firearm, creating a gas flow interruption that slows down exiting gases to reduce sound. Second, it includes a "disc" (also referred to as a shutter) placed between the core and the end cap, which likely serves to further control or restrict gas flow at the muzzle end. The system also specifies a muzzle adapter for attaching the suppressor to the firearm's barrel.
