This is a replacement base for the Ergo MAST Modular Armorer STand System. It accepts the MAST insert module that goes inside your pistol’s magwell to create a free-standing benchtop stand that supports the gun for maintenance, display, cleaning, or storage. The Ergo MAST base is made of reinforced molded polymer, with two hardened stainless steel pins that lock the insert module into the base. This is the Ergo MAST base ONLY – you will need to purchase the MAST insert modules separately. Mfg: Ergo Grips
