The aluminum ESG grip is unlike any other grip on the market. This grip has a durable CNC aluminum build. One can run different regulator setups and lines on the fly, as well as store a battery in the grip. Different versions use the Wolverine Storm regulator and Polarstar regulator, as well as the bulge or straight front look.
