A firearm barrel with non-metal outer sleeve preferably includes an elongated tube, a first non-metal tube, a second non-metal tube, a sleeve nut and a coupler bushing. A first raised sleeve support section and a raised coupler section are formed on the elongated sleeve. The raised coupler section is formed in substantially a middle of the elongated tube. The bushing inner diameter is sized to slidably receive an outer diameter of the raised coupler section. The first and second non-metal tubes include a tube inner diameter and a plurality of openings formed through a wall thereof. The tube inner diameters are sized to slidably receive an outer diameter of the first raised sleeve support section and each end of the coupler bushing. The sleeve nut retains the first and second non-metal tubes and the coupler bushing on the elongated tube. A second embodiment includes a single non-metal tube.

A Universal Custom Recoil Solution will comprise of, a provided Firearm or barrel, prismatic shaped shell housing mounted or connected to the Gas Block Base, a Gas Block Base with pathways to direct firearms gas pressure from firing bullet into device interior pushing a Counter Weight, and Spring to counter act the firearms recoil when fired. This device is fitted to or around a provided barrel where the Counter Weight and spring are mounted on and reciprocate from front to back of the systems interior volume. The systems main function is to create a counter balance to the firearms kinetic energy by providing a moving mass, to counter the recoil from the firearms action movement when firing. The gas pressure is also expelled and redirected allowing the device to cycle synergistically with the firearm actions.

An upper receiver assembly includes a barrel, a suppressor body operable to couple to a muzzle end of the barrel, and a first sleeve disposable about the barrel and the suppressor body, wherein the barrel includes one or more longitudinally oriented ribs extending radially from a barrel body having a bore formed therein, and a second sleeve surrounding the first sleeve, the second sleeve comprising a fibrous thermally insulating material.

A suppressor assembly attachable to a firearm is disclosed. The firearm may include a barrel and a muzzle end. The suppressor assembly may include a gas block positioned about the barrel, an outer tube attached to the gas block, and a baffle attached to the muzzle end. The baffle may push against the outer tube to compress the outer tube and apply tension to the barrel.

An improved design of a two-piece gas block for a semi-automatic rifle barrel. The improvement consisting of integrated attachment features that allow for a smaller overall size and a more reliable fit around a rifle barrel. The integrated attachment features contain minimal hardware for assembly; therefore, easier to assemble and disassemble. These attachment features consist of built-in interlocking protrusions and recesses in each half of the two-piece gas block. When assembled, the interlocking protrusions and recesses radially secure both halves together around a rifle barrel. Once both halves are assembled, fitted pins are then inserted through the interlocking protrusions and recesses to secure both halves axially to each other.

Quick take-down firearms and methods of using quick-take down firearms. The quick-take down includes an upper receiver coupling and a barrel coupling. The quick take-down can be unlocked by sliding a sliding lock collar in a translational motion to an unlocked position to release locking elements from a locked configuration. In the unlocked position, a barrel and handguard may be installed onto and removed from the upper receiver of the firearm. Releasing the sliding lock collar returns it to a locked position, securing the barrel and handguard to the upper receiver.
