The STOPBOX USA Chamber Lock Pro in Red for Shotgun (stopbox-lockshotgun) is a bright red chamber safety device engineered to fit 12-gauge and compatible shotguns, providing a highly visible physical block that prevents the shotgun from chambering a shell. The vivid red color provides instant visual and tactile confirmation that the shotgun is in a safe, disabled state — critical for storage in homes with children, in gun shops, and during transport. An important secondary safety device for responsible shotgun owners. Sized to fit standard 12-gauge chambers.
