A brand of gun safes sold nationwide is under recall because of a malfunction that can allow someone to open it without a key or combination, giving anyone access to the firearms inside.

The Stack-On Sentinel gun safe has a bolt malfunction, according to the voluntary recall by Alpha Guardian. It was sold at Dick's Sporting Goods from November 2018 through December 2018 for about $700.

The black steel safe is used to store up to 10 firearms or other valuables, the company said. The style number FSS18-64-MB-E-S can be found on the shipping packaging. The “Sentinel” name appears on the front of the safe.
