The Real Avid AR15 Smart Mat is a gun cleaning mat on steroids. It's large enough to handle a field-stripped AR15 with the visible instructions to guide you. The ingenious attached parts tray ensures your pins, bolts and springs are never lost again. And its no-slip backed mat, featuring an oil-resistant surface, allows you to properly clean your gun without ruining the kitchen table. This takes gun mats to the next level.
