Patent number: 11920884Abstract: 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.Type: GrantFiled: June 25, 2021Date of Patent: March 5, 2024Assignee: Devhold Inc.Inventor: Darryl S. Lee

Patent number: 11268779Abstract: 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.Type: GrantFiled: September 25, 2020Date of Patent: March 8, 2022Assignee: Devhold Inc.Inventor: Darryl S.

Patent number: 11022395Abstract: 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.Type: GrantFiled: December 18, 2019Date of Patent: June 1, 2021Assignee: CTWIP LLCInventor: Darryl S. Lee

Patent number: 10302384Abstract: 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.Type: GrantFiled: June 16, 2017Date of Patent: May 28, 2019Assignee: DBDROP Inc.Inventor: Darryl S.
