  • Publication number: 20250237471
    Abstract: A firearm forearm assembly is provided. Generally included is a forearm retainer that is a flexible component installed in the forearm, which is then momentarily deflected to admit each action bar. Once the forearm assembly is installed in the firearm, the firearm's magazine tube is introduced and prevents further deflection of the retainer, thus locking the forearm assembly together during use. As a result, the forearm assembly is easily disassembled by the user without the use of tools by deflection of the retainer and removal of the action bars. But at the same time, the integrity of the firearm is preserved during operation.
