Ensure your rifle is clearly safe and range-compliant with this AICS Chamber Blocker / Safety Flag, designed to insert directly into the magwell of rifles that use AICS-pattern magazines. This simple but effective device provides a highly visible indicator that the firearm is unloaded while also physically preventing the bolt from closing.

When installed, the chamber blocker extends upward from the magazine well into the action, blocking the bolt from fully closing. This provides an additional level of safety confirmation for range officers, hunting partners, or anyone nearby by making it immediately obvious that the rifle cannot be chambered.

Designed to work with all rifles that accept AICS-style magazines, the blocker installs quickly through the magwell just like a magazine and removes just as easily when you’re ready to shoot.

Each chamber flag is precision 3D printed using tough, resilient materials, making it durable enough for repeated range use while remaining lightweight and easy to carry in your range bag.

To make safety status easy to see and match your setup, the blocker is available in multiple high-visibility color options.
