The Ultra 20 TekMat is large enough to handle a fully disassembled handgun with room to spare for tools and accessories. The extra thick .25 padding 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 your firearm. The ultra-soft, oil and water-resistant surface helps protect your firearm from scratches while the diagrams and illustrations help with cleaning, disassembly and are just plain fun to look at.
