BACKGROUND OF THE INVENTION

Field of Invention

The present invention relates to firearm suppressor technologies, specifically to suppressors incorporated into ported barrel systems that are designed to be user-serviceable for maintenance and cleaning.

Background of the Invention

The field of firearm noise suppression encompasses various systems designed to mitigate the acoustic and visual signatures generated during firearm discharge. Many devices in this field are engineered to contain and control the energy of rapidly expanding gases, thereby reducing noise levels and minimizing muzzle flash. Such systems contribute to operator safety, protect hearing, and facilitate clearer communication in high-stress or tactical environments. Over time, designers have sought to balance performance with overall system robustness and simplicity, resulting in a range of configurations that address the demands of both recreational and professional users.

In many applications, the goal of a firearm suppressor is not only to lower sound intensity but also to enhance user effectiveness by stabilizing recoil and reducing disruptive visual cues. These systems are highly beneficial in settings where environmental noise control and personal protection are prioritized, providing operators with improved situational awareness and operational efficiency. Achieving these benefits often requires a thoughtful integration of design elements that manage gas expansion, absorb recoil energy, and maintain proper alignment with the firearm's barrel, all while considering ease of handling and safe storage.

A general challenge with many integrated suppression systems is their limited serviceability. Frequently, these devices are configured as a single, fixed assembly that does not permit routine cleaning or maintenance. As a result, the accumulation of residues, such as carbon or metallic debris, can gradually impair suppression performance, eventually necessitating the complete replacement of the unit. This fixed design approach, while initially simplifying installation, can lead to increased long-term operating costs and extended periods during which the firearm is required to remain out of service for maintenance purposes.

More specifically, many existing integrated systems require users to dispose of and replace the entire suppressor once performance is degraded rather than allowing for straightforward servicing. This creates additional logistical burdens in environments where regulated items are replaced in full, thereby increasing downtime and expense. Furthermore, the challenges of maintaining precise internal alignment and preventing component interference can further undermine overall efficiency. Such issues highlight the importance of solutions that enable easier maintenance while preserving the functional integrity and cost-effectiveness of suppression technology.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

The field of firearm suppressor technology has long focused on addressing the challenges associated with reducing noise, muzzle flash, and recoil during firearm discharge. Conventional suppressors, particularly those designed for ported barrel systems such as those used in MP5SD firearms, face several notable limitations. These suppressors are often sealed, non-serviceable units that accumulate carbon, lead, and other debris over time, leading to diminished performance. Once these suppressors become unusable, they are typically discarded and replaced, which creates additional burdens for items regulated under the National Firearms Act (NFA). The process of acquiring a replacement suppressor frequently involves extended registration periods, increased costs, and logistical difficulties. Furthermore, many existing suppressors rely on the use of costly and less readily available subsonic ammunition to achieve effective noise reduction, adding further complexity to their operation. Misalignment of internal components in traditional suppressors can also lead to baffle strikes, resulting in damage to the suppressor and impairing its functionality.

The present disclosure addresses these deficiencies by introducing a suppression apparatus that is designed to be user-serviceable, thereby extending the operational lifespan of the suppressor and reducing the need for frequent replacement. Unlike conventional designs, the disclosed suppressor can be disassembled for cleaning and maintenance, allowing users to preserve their investment in the original NFA-registered item. The apparatus incorporates a specialized baffle stack design featuring k-shaped baffles with interlocking mouse holes, which ensures precise alignment with the barrel bore and prevents baffle strikes. This alignment not only protects the suppressor from damage but also enhances its performance and reliability.

Furthermore, the described technology eliminates the need for subsonic ammunition by utilizing an innovative expansion chamber and blast chamber configuration. The expansion chamber, integrated into the suppressor tube, bleeds off gases from supersonic rounds, reducing their velocity to subsonic speeds. This feature allows users to employ readily available and cost-effective supersonic ammunition while achieving the same noise reduction benefits. The blast chamber facilitates the cooling and expansion of remaining gases, while the k-shaped baffles direct and dissipate gas energy through multiple edges and angles, further reducing noise and muzzle flash. The modular design of the suppressor enables users to adapt the overall length and performance by adjusting the number of baffles, providing flexibility for different firearm platforms and calibers.

By integrating user serviceability, improved alignment, and compatibility with supersonic ammunition, the described technology provides a notable advancement over existing suppressors. This approach lowers long-term costs, streamlines maintenance, and delivers reliable performance, presenting an enhanced option for both recreational and professional firearm users.

Broadly, embodiments of the present invention comprise integral suppressor apparatus(es) for use on firearms with ported barrel systems. The integral suppressor apparatus(es) of the present invention include a plurality of components such as a tube(s), or housing(s), a plurality of baffles, barrel cap(s), an end cap(s), a plurality of spacers, and barrel support(s). In embodiments, two or more components can be combined, or made integral to one another, to form additional components.

Broadly, components of the present invention are formed from materials such as, but not limited to, steel, aluminum, or titanium, which can be anodized for a hard type III finish. Additionally, the present invention can be manufactured and assemble utilizing any technique known in the art.

Broadly, an embodiment of the present invention provides an integral suppression apparatus capable of being disassembled for servicing, such as maintenance and cleaning. The present invention extends the useful life of integral suppression apparatuses, and eliminates the inefficiencies associated with prior art integral suppression apparatuses.

Referring now to FIG. 1-3, a first embodiment of the present invention is illustrated. FIG. 1 shows an assembled view of a first embodiment of a suppression apparatus 100, designed for use with ported barrel systems. The suppression apparatus 100 is configured to reduce noise, muzzle flash, and recoil during firearm discharge while being user-serviceable for maintenance and cleaning.

The suppression apparatus 100 includes a long tube 102, which serves as the primary housing of the suppressor. The long tube 102 is substantially cylindrical and is designed to enclose the internal components of the suppressor, such as baffles 202, spacers 204 and 208, and barrel support nut 206, which are not visible in this figure. The long tube 102 is of sufficient length and diameter to house these internal components while maintaining alignment with the firearm's barrel. In some embodiments, the exterior of the long tube 102 may feature knurling or other surface textures to assist with gripping during installation and removal.

A barrel cap 104 is disposed at one end of the long tube 102. The barrel cap 104 serves as a coupling mechanism that secures the suppressor to the ported barrel of the firearm. In some embodiments, the coupling mechanism may include internal threading, such as female threading, that matches the threading on the firearm's barrel, such as male threading, ensuring a secure and precise fit. Advantageously, the barrel cap 104 aids in the alignment of the suppression apparatus 100 with the barrel bore, reducing the risk of baffle strikes and ensuring optimal performance.

An end cap 106 is located at the opposite end of the long tube 102. The end cap 106 functions to enclose the internal components of the suppressor and provides an exit aperture for the projectile. In some embodiments, the end cap 106 may include features such as threading or compression mechanisms to secure the internal components, such as baffles 202, within the long tube 102. In embodiments, the compression mechanism is a compression washer disposed between end cap 106 and the one or more baffle(s) 204 thereby providing secure fitment of the internal components of suppression mechanism 100. The end cap 106 may also contribute to the suppressor's noise reduction capabilities by incorporating additional baffling or gas redirection features.

The configuration of the suppression apparatus 100, as shown in FIG. 1, highlights the modular and user-serviceable design. Both the barrel cap 104 and the end cap 106 are removable, allowing access to the internal components for cleaning and maintenance. This design extends the operational lifespan of the suppressor and reduces the need for frequent replacement, addressing a notable limitation of conventional suppressors.

FIG. 2A-B show exploded views of the suppression apparatus 100, illustrating the internal components that contribute to the functionality of the apparatus. The one or more baffle(s) 202 are designed to manage the flow and expansion of gases generated during firearm discharge. The one or more baffle(s) 202 are configured in a k-shaped design, which includes interlocking mouse holes to ensure precise alignment with a barrel bore of a firearm. In embodiments, the one or more baffle(s) 202 have a substantially conical component, such as a truncated cone, affixed to one or more cylindrical bases. In embodiments, the truncated cone is affixed to the one or more cylindrical bases at its apex, and the interlocking mouse holes are disposed through the one or more cylindrical bases to an outer surface of the truncated cone proximal to its apex. This alignment is necessary for preventing baffle strikes, thereby protecting the suppressor apparatus 100 from damage and preserving its operational effectiveness. The one or more baffle(s) are be adapted to direct the gas energy against and through multiple edges and angles reducing the velocity and energy as it travels through the numerous baffle chambers.

The short spacer 204 serves as a blast chamber within the suppression apparatus 100. Positioned between the one or more baffle(s) 202 and the barrel support nut 206, the short spacer 204 allows for the expansion and cooling of remaining gases after the initial discharge. This cooling effect contributes to the reduction of noise and muzzle flash, enhancing the suppressor's effectiveness in various operational environments. While the short spacer 204 is shown as an independent component, it is contemplated that the short spacer 204 can be integral with a first one of the one or more baffle(s) 202, as illustrated in FIG. 2B. Said differently, the short spacer 204 can be permanently affixed to the first baffle of the one or more baffle(s) 202 forming an integral baffle with blast chamber 210.

In the configuration illustration in FIG. 2B the short spacer 204 can be permanently affixed to the first baffle of the one or more baffle(s) 202 forming an integral baffle with blast chamber 210. In this embodiment, an end of short spacer 204 proximate to, or contacting, the base of the first of the one or more baffle(s) 202 can be affixed, or otherwise joined to the base. Alternatively, the first one of the one or more baffle(s) 202 can be manufactured to have short spacer 204 monolithically extending from its base forming the integral baffle with blast chamber 210.

The barrel support nut 206 maintains the alignment of the suppression apparatus 100 with the firearm's barrel. The barrel support nut 206 secures the ported barrel and ensures that all internal components remain properly aligned with the bore. Maintaining this alignment is important for the suppression apparatus' functionality, as it helps prevent component interference and potential damage during operation.

The long spacer 208 functions as an expansion chamber within the suppression apparatus 100. The long spacer 208 is designed to bleed off gases from the fired projectile cartridge, reducing their velocity to subsonic speeds. By lowering the speed of these gases, a vacuum effect is created, which pulls excess gases out through the ports of the ported barrel before the chamber cycle opens. In embodiments, a ported barrel of a firearm is inserted into suppression apparatus 100, such that long spacer 208 bleeds off gasses expelled from the ports of the ported barrel. The long spacer 208 contributes significantly to enabling the use of supersonic ammunition while achieving effective noise reduction, removing the requirement for expensive subsonic rounds. While the long spacer 208 is shown as removable from the long tube 102, it is contemplated that the long spacer 208 can be integral to the long tube 102. Said differently, the long spacer 208 can be permanently affixed to an inner surface of the long tube 102, or alternatively the long tube 102 can be manufactured such that the inner surface of the long tube 102 has a first inner diameter and a second diameter inner with the second inner diameter being smaller than the first, and being located on the inner surface of the long tube 102 where the long spacer 208 would be placed, as illustrated in FIG. 2B.

Together, these components—baffle 202, short spacer 204, barrel support nut 206, and long spacer 208—work in concert to provide improved suppression capabilities, allowing for user serviceability and maintenance, which extends the operational lifespan of the suppression apparatus 100.

FIG. 3 shows a cross-sectional view of the suppression apparatus 100, illustrating the internal configuration and interconnection of the structural components of the apparatus. The suppression apparatus 100 is designed to reduce noise, muzzle flash, and recoil during firearm discharge while being user-serviceable for maintenance and cleaning.

The long tube 102 serves as the primary housing of the suppression apparatus 100. The long tube 102 encloses and aligns the internal components, ensuring proper functionality and structural integrity. This component is configured to maintain alignment with the firearm's barrel, providing a stable and secure enclosure for the internal elements.

The one or more baffle(s) 202 are aligned as a baffle stack within the long tube 102 and manage the flow and expansion of gases generated during firearm discharge. The baffle stack 202 includes a series of k-shaped baffles, each designed with interlocking mouse holes to achieve precise alignment with the barrel bore. This alignment helps prevent baffle strikes, thereby safeguarding the suppressor from damage and supporting operational performance. The baffle stack guides and disperses gas energy through multiple edges and angles, contributing to the reduction of noise and muzzle flash.

Adjacent to the baffle stack is the short spacer 204, configured as a blast chamber. The short spacer 204 allows for the initial expansion and cooling of gases after discharge, contributing to the overall noise reduction capabilities of the suppression apparatus 100. The short spacer 204 is positioned between the baffle stack and the barrel support nut 206.

The barrel support nut 206 is located further along the cross-section and is significant in maintaining the alignment of the suppression apparatus 100 with a firearm's barrel. The barrel support nut 206 secures the ported barrel and ensures that all internal components remain properly aligned with the bore, preventing component interference and potential damage during operation.

The long spacer 208 is positioned between the barrel support nut 206 and the barrel cap 104. The long spacer 208 functions as an expansion chamber, designed to bleed off gases from the fired projectile cartridge. In embodiments, a ported barrel of a firearm is inserted into suppression apparatus 100, such that long spacer 208 bleeds off gasses expelled from the ports of the ported barrel. This process reduces the velocity of the gases to subsonic speeds, creating a vacuum effect that pulls excess gases out through the ports of the ported barrel before the chamber cycle opens. While the long spacer 208 is shown as removable from the long tube 102, it is contemplated that the long spacer 208 can be integral to the long tube 102. Said differently, the long spacer 208 can be permanently affixed to an inner surface of the long tube 102, or alternatively the long tube 102 can be manufactured such that the inner surface of the long tube 102 has a first inner diameter and a second inner diameter with the second inner diameter being smaller than the first, and being located on the inner surface of the long tube 102 where the long spacer 208 would be placed. This feature enables the use of supersonic ammunition while achieving effective noise reduction.

The barrel cap 104 is located at one end of the long tube 102 and serves as a coupling mechanism that secures the suppression apparatus 100 to the firearm's ported barrel. The barrel cap 104 ensures a secure and precise fit, aiding in the alignment of the suppression apparatus 100 with the barrel bore. In embodiments, barrel cap 104 is formed of one or more cylinders having an inner bore defining an inner surface and one or more outer surfaces. In embodiments, the inner surface includes an attachment mechanism, such as threading for affixing the suppression apparatus 100 to a bore of a firearm. Additionally, at least a portion of the one or more outer surfaces includes an attachment mechanism, such as threading, i.e. male threading, for securing barrel cap 104 to long tube 102, wherein long tube 102 has an attachment mechanism, such as threading, i.e. female threading, disposed on an inner surface thereof, proximate to a first opening.

At the opposite end of the long tube 102 is the end cap 106. The end cap 106 encloses the internal components of the suppression apparatus 100 and provides an exit aperture for the projectile. The end cap 106 may also include features that contribute to the suppressor's noise reduction capabilities, such as additional baffling or gas redirection mechanisms. The end cap 106 functions alongside a compression washer (not shown in this figure) to secure the internal components, ensuring the components remain in place during operation. In embodiments, end cap 106 is formed of one or more shapes, and has an inner bore defining an inner surface and the one or more shapes have one or more outer surfaces. In embodiments, at least a portion of the one or more outer surfaces includes an attachment mechanism, such as threading, i.e. male threading, for securing end cap 106 to long tube 102, wherein long tube 102 has an attachment mechanism, such as threading, i.e. female threading, disposed on an inner surface thereof, proximate to a second opening.

The suppression apparatus 400 includes a short tube 402, which serves as the primary housing of the suppressor. The short tube 402 is substantially cylindrical and is designed to enclose the internal components of the suppressor, such as baffles 502, spacers 504 and 508, and barrel support nut 506, which are not visible in this figure.
