Product Recall Notice: AR-15 Chamber Lock Pro

Important Safety Recall

We’ve identified a potential issue with select AR-15 Chamber Lock Pro units. In some cases, the lock can be forcibly removed from a firearm, allowing unauthorized or unintended access to the firearm, posing a risk of serious injury or death. In coordination with the U.S. Consumer Product Safety Commission, we are initiating a recall of the StopBox AR-15 Chamber Lock Pro. We are taking this action proactively to ensure the safety and satisfaction of our customers. For full recall: cpsc.gov/Recalls.

Root Cause

This issue resulted from a change in CNC fixturing that impacted a precision milling operation. Due to tight tolerances, this defect was not initially apparent.

  • The issue has been corrected in our CNC machining process.
  • Custom gauges have been implemented to measure the affected feature.
  • Post-CNC quality checks now include this inspection step.
  • Final product testing now includes verification of locking tooth resistance.

Units shipped between June 2 and July 15, 2025 can be affected. If your product was fulfilled/shipped during this period, please request a replacement or refund.
