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 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 and disassembly. This tongue-in-cheek mat pokes fun at the way liberal's and anti-gun advocates describe the AR-15. It calls out how ridiculous their claims are and the misinformation they are propagating. This is the perfect addition to your man cave or better yet, send it to your gun-hating liberal friends.
