AR-15 Builder's Mat

Usually ships the same day or the next business day!

This mat is the perfect complement to your AR-15 or AR-10 workspace. The soft polyester top-layer material protects your firearm and its parts from any scratches or damage.  As a bonus, it features a waterproof coating to keep the mat from absorbing oils, grime, and chemicals, and your workspace clean. The underside of the mat is made of neoprene rubber to ensure your work surface won't slip while you work.


  • An exploded view diagram of an A2 style AR-15*
  • A detailed list of each and every part that makes up your AR rifle
  • Measures 36 inches wide x 12 inches tall x 1/8 inch thick
  • Waterproof Soft Polyester Top Layer - Protects your firearm from dings and scratches
  • Neoprene Rubber Backing - Keeps things in place on your work surface

*The exploded view diagram on our builder's mat was based on the A2-style AR-15 as built by Colt. However, as it goes with all AR-15s, the parts are equivalent and will be 90-95% in line with your own AR rifle.

Care Instructions: Over time, your build mat may accumulate dirt, chemicals, or oil from cleaning or working on your firearm. To clean your build mat, simply throw it in the washing machine on a gentle cycle, then set it out to air dry.  Once fully dry, your builder's mat will be clean again and good to go!
