The Diplomat Maintenance Mat is the perfect in-between size. CrossTac joined their Pro Maintenance Mat and their Rifle Maintenance Mat to create this perfectly sized cleaning mat / maintenance mat for modern rifles. You get a solvent and oil proof grippy work surface, a place to store cleaning supplies and parts (3 actually) a place to stick random metal parts on the magnets so they don't roll off the bench or blow away. The 6 rare earth magnets embedded in the perimeter are so strong, it sticks to anything like crazy, and allows you to put the mat on a tailgate, hood, or other surface without the wind carrying it all away.
