Sisk Rifles Manufacturing will lead the way into the next generation of firearm attachments. Our innovative thinking has allowed us to improve the functionality and safety of weapons in areas where most of the industry have failed to improve in many years. The HEPR expands cover capabilities, the patented stock allows users to fire while wearing a gas mask unhindered protecting from Covid-19, and the TARS systems give users quick-swap functionality helping them to adapt to mission needs on the spot.
