The CAR816 A2 is chambered in 5.56 x 45mm NATO. The short-stroke, push rod, gas piston design is controlled by an adjustable gas valve with three positions. Position one is for normal operation. Position two is for operation in adverse conditions, low impulse ammunition or when the system becomes fouled. Position three is for normal operation with an affixed suppressor, and allows for reliable cycling of the action. The CAR816 A2 is now available to U.S. consumers in a semi-automatic configuration, and ships standard with a 16” barrel. Proudly manufactured in the United States.
