The 17″ TekMats are large enough to handle a fully disassembled handgun with room to spare for tools and accessories. The 1/8″ padding on these mats not only provides a premium feel and high level of quality but it offers extra protection from any rough handling or drops while working on firearms. The ultra soft, oil and water-resistant surface helps protect firearms from scratches while the diagrams and illustrations help with cleaning and disassembly.
