Abstract: A wipe-cutting tool integrated into a firearm or firearm accessory, or component thereof, which can be replaced in the field. The muzzle accessories may include a suppressor, a brake, a compensator or a flash suppressor. The components may include an endcap, the end of an accessory, a muzzle or a baffle. Cutting blades are integrated into the firearm or muzzle accessory and may be integrally formed with the suppressor or compensator tube as well as with a muzzle end cap attached to the tube. When pressed into a substrate of material suitable to form a wipe the cutting blade separates a wipe from the substrate which can be readily inserted into the suppressor or compensator at the muzzle end.

Abstract: A conversion kit for installation into weapon to replace the service barrel with a sub-caliber barrel for firing reduced energy training cartridges. The conversion kit includes a barrel sleeve, a barrel support and a collet disposed between in the barrel support for fixedly securing the barrel sleeve therein. The collet is disposed in a double tapered bore formed in the barrel support for fixedly securing the barrel sleeve at both ends of the collet into the barrel support. A flash hider, which has been removed from the service barrel, is threadably received in the barrel support and functions as a collet nut for clamping the collet onto the barrel sleeve.

Abstract: Methods and systems are provided for firearm sound suppressors including a gas deflector. In one example, a suppressor comprises a housing, a projectile entrance, a projectile exit, one or more baffles, and a deflector chamber. The deflector extending outward from the housing and the deflector curving around a central axis of the suppressor.

Abstract: A disclosed energy regulation and release device capable of balancing energy signatures of flash and sound with practical and tactical concerns of length, recoil and modularity. The energy regulation and release device may include a primary device and a secondary device, and each of those may include a series of internal chambers designed and configured to create a reduction in energy release. The device may thereby achieve a reduction of the signature of a transition of energy from a muzzle of a weapon into an unrestricted atmosphere (internal to external), including a positive buffering, reduction or diminishment of flash, heat, and sound.

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.

Abstract: A modular suppressor kit includes a modular suppressor and suppressor tool. The modular suppressor includes a barrel attachment portion that has a central passage. The barrel attachment portion is configured to attach to a firearm barrel. The modular suppressor includes a cap portion that has a central passage. The modular suppressor includes a body portion that has an internal baffle structure and an expansion chamber. The body portion is attachable to, and separable from, the barrel attachment portion and the cap portion. The body portion defines a central passage that is alignable with the central passage of the barrel attachment portion and the central passage of the cap portion. The suppressor tool has an engagement feature for engaging with at least one of the barrel attachment portion, cap portion, and body portion.
