The big one runs $380 and the little one runs $280. They of course can be modded with accessories tailored to a wide variety of gun configurations.
They are designed to work with standard 2×4 walls and the bookends are the fixture arms. The tops are cherry-finished hardwood and the shelf is suspended with pneumatic struts to ensure smooth opening. It uses hidden magnet keys to unlock.
Currently Tactical Walls is taking pre-orders on their Tactical Shelves and expect delivery to begin in February.
