By modular gun walls, we mean that our gun walls were designed to allow flexibility when designing and rearranging your gun display. Our 2 foot and 4 foot slatwall panels come as individual rails that can be stacked vertically or joined end to end horizontally. This helps you create a gun wall that is precisely the size you need, with the ability to easily expand as your firearm collection grows. Our slatwall gun fixtures allow you to quickly rearrange the layout of your firearms.
