AR-15 Chamber Lock Pros Recalled Nationwide Due to Serious Injury and Death Risk

StopBox USA is recalling approximately 300 AR-15 Chamber Lock Pro firearm locks due to a manufacturing defect that could allow unauthorized access to a firearm, posing a significant risk of serious injury or death. The locks, which are designed to secure the chamber of AR-15 style rifles, were sold between June 2 and July 15, 2025.

The recalled products are AR-15 Chamber Lock Pro firearm locks manufactured by StopBox USA, located in Spokane Valley, Washington. These devices are made from anodized aluminum and feature five buttons, with the StopBox “S” logo and “CHAMBER LOCK PRO AR-15” laser etched on the back. They were sold in red and black. Consumers can identify if their product is affected by checking the shipping date, which can be obtained by contacting StopBox USA. The affected products were sold directly by StopBox USA, both in-store and online, as well as through dealers nationwide during the specified shipping period. The retail price was approximately $150.

Consumers who have purchased these recalled chamber locks are urged to immediately cease using them and to secure their firearms through alternative means. StopBox USA is offering a remedy for affected customers, which includes a full refund or a replacement AR-15 Chamber Lock Pro. To initiate the return process, consumers will receive a prepaid shipping label and instructions from StopBox USA.

The hazard identified with these locks is a manufacturing defect that allows the device to be forcibly removed. This malfunction could compromise the security of the firearm, potentially leading to unauthorized or unintended use, and thereby increasing the risk of serious injury or death. To date, no incidents or injuries have been reported in connection with this recall.
