Adding to its unparalleled functionality, the HCS also offers all of the cosmetic and ergonomic benefits of some of the most popular firearm configurations for unbeatable compactness and close quarters performance. With the included remote airline fitting, you will have the ability to swivel the fitting on the bottom of the stock. This fitting will accept any 1/8"NPT air fitting.
