  • Patent number: 10527379
    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: 10508879
    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: 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.

  • Patent number: 10274279
    Abstract: A firearm adapter that can attach to a rail secured to a firearm barrel and can quickly, accurately, securely, and concentrically attach a suppressor or suppressor extension to the firearm barrel even when the firearm barrel includes a muzzle device, such as a flash hider. The adapter is tool-less and attaches a suppressor or other muzzle device to a variety of rail equipped firearms with different geometries while providing strong securement and proper alignment.
