  • Patent number: 11920884
    Abstract: A universal firearm shield adapted to attach to a firearm suppressor. Suppressors fail to dampen all of the effects of firearm discharge, leaving behind residual effects that may be noticeable. The shield dampens the residual effects of firearm discharge that are not captured by the suppressor. The residual effects are captured by the shield and dispersed throughout one or more interior chambers. The shield easily, quickly, and securely couples to suppressors of varying geometries due to the slidably adjustable components of the shield. The shield is configured to surround the suppressor and axially align with the suppressor. As such, the muzzle of the firearm axially aligns with the shield, the suppressor, and the barrel for an unobstructed projectile path during discharge.

  • Patent number: 11268779
    Abstract: A fast-attaching, self-aligning, easily adaptable and preferably tool-less suppressor adapter. The novel adapter attaches to the barrel of a firearm while precisely aligning the barrel and adapter using a set of compression feet equidistantly spaced around the perimeter of the adapter. The device is adapted to attach to a wide range of barrel diameters via an easy to fit and inexpensive to manufacture fitment sleeve. Thus, the adapter can be manufactured in a single size and work with most firearms. In addition, the device attaches to the smooth section of barrel thereby eliminating the need for permanently modifying a firearm by threading the barrel.

  • Patent number: 11022395
    Abstract: A flexible fit, easy to attach and align, firearm adapter that allows secure fitment of a muzzle device, such as a suppressor, to a broad range of firearm sizes and shapes, with a single device. These firearms would include difficult to fit barrel profiles that in many cases would go unsuppressed without this improvement over the prior art. An embodiment includes an anchor securable to a smooth section of a firearm barrel and a housing adapted to engage the anchor. The anchor and housing are sized to reach over or around barrel obstructions. An embodiment includes an alignment guide to bring the barrel into axial alignment with the muzzle device.

  • Patent number: 10996015
    Abstract: A fast-attaching, self-aligning, easily adaptable firearm adapter. The novel adapter attaches to the barrel of a firearm while precisely aligning the barrel and adapter using a concentric constriction sleeve along the barrel and a barrel guide to funnel firearm muzzle. The device is adapted to attach to a wide range of barrel diameters via an easy to fit and inexpensive to manufacture fitment sleeve. Thus, the adapter can be manufactured in a single size and work with most firearms. In addition, the device attaches to the smooth section of barrel thereby eliminating the need for permanently modifying a firearm by threading the barrel.

  • Patent number: 10746492
    Abstract: A universal firearm adapter configured to mount to the frame of a firearm. The adapter easily, quickly, accurately, securely, concentrically and repeatably, with or without tools, attaches a suppressor or suppressor adapter to the frame or rail system of a firearm. The adapter includes a rail attachment configured to attach to a plurality of dimensionally inconsistent frames/rails and a bore alignment assembly. Moreover, the adapter is configured to axially align the adapter bore with the barrel bore regardless of the dimensional and axial inconsistencies of the barrel and its bore. The bore alignment assembly preferably includes a suppressor mount axially aligned with the adapter bore thereby ensuring that the suppressor is axially aligned with the bore of the barrel.

  • Patent number: 10739098
    Abstract: A fast-attaching, self-aligning, easily adaptable and tool-less firearm adapter. The novel adapter attaches to the barrel of a firearm while precisely aligning the barrel and adapter using a concentric constriction sleeve along the barrel and a longitudinal compression barrel guide at the muzzle. The device is adapted to attach to a wide range of barrel diameters via an easy to fit and inexpensive to manufacture fitment sleeve. Thus, the adapter can be manufactured in a single size and work with most firearms. In addition, the device attaches to the smooth section of barrel thereby eliminating the need for permanently modifying a firearm by threading the barrel.

  • Patent number: 10352642
    Abstract: A firearm adapter that attaches a muzzle device, such as a suppressor to a broad range of firearm sizes and shapes. The adapter can securely attach and align a suppressor to a wide range of barrel diameters and profiles, including, those barrels with various obstructions, protrusions and geometries. An embodiment of the device reaches over or around barrel obstructions to securely attach a housing to an anchor on an unobstructed section of the barrel and further compresses an alignment surface against the muzzle to create longitudinal and concentric alignment between the barrel and the suppressor.

  • Patent number: 10302384
    Abstract: A firearm barrel fitment sleeve and method of use. The fitment sleeve is preferably fast-attaching, self-aligning, and securable without the need of a tool. The novel fitment sleeve allows a single firearm accessory adapter to be used with a wide range of firearm barrels by temporarily modifying the size of the barrel diameter without permanently modifying the structure of the firearm. The fitment sleeve is inexpensive and preferably includes a longitudinally extending slot in the lateral wall making a single fitment sleeve usable on a wide variety of barrel diameters. Additionally, the fitment sleeve is heat resistant to avoid melting and/or catching fire when the barrel increases in heat during operation.
