The Real Avid Master Armorer's Mat is an oversized padded bench mat built for AR-15 builds, maintenance and cleaning. At roughly 47.25" x 19.63", it covers the full length of a rifle and protects both the firearm finish and your work surface. The surface resists oil and solvent, so cleaning sessions do not soak through, and the non-skid backing keeps the mat in place while you torque, drift pins or scrub a bolt carrier. A screen-printed AR-15 parts schematic sits right on the mat, which helps when you are reassembling a lower or identifying a small part. Lay the mat out before you start so small springs and detents land on the pad instead of the floor. Features: Oversized padded mat, approximately 47.25" x 19.63" Oil- and solvent-resistant surface Non-skid backing Screen-printed AR-15 parts schematic Integrated parts tray Detachable small-parts case Magnetic micro tool A workbench accessory for assembly and maintenance. Wipe the surface clean after use to keep solvents from pooling in the parts tray.
