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.

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.

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.

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.
