Carbon arms FSL shotgun caddies work with ELS plates and are a direct bolt on. I believe their other products will work as well. I use a bladeteck holster and mount it to the belt using a QLS attachment. Belt had to be drilled to add QLS plate. Center of mass for mag pouches and bladeteck for AR pouches round out my belt and both are a direct bolt on to the ELS plate. U will need to make a trip to the hardware store for different mounting hardware. Hope this helps.
