Christensen Arms CA-15 G2 modern sporting rifles feature CA's trademark carbon fiber in critical components to reduce weight and increase structural integrity.
This is particularly relevant to AR15-type rifles, which tend to be front-heavy due to the use of long, heavy, metal handguards.
Barrel mass is also a consideration; in a traditional AR15-type rifle, the shooter must balance their desired muzzle velocity with the weight that will be imparted by a longer, heavy-contour steel barrel.
The CA-15 series,alleviates this issue by offering a composite barrel (button-rifled, 416R stainless steel, wrapped in Aerograde carbon fiber).
The result is a target-contour barrel that weighs considerably less than shorter, all-steel barrels of the same (or even thinner) contour.
These features yield a light-weight, high-precision semi-automatic rifle which is, in the case of the G2 series, chambered in .223 Wylde, enabling the safe use of 5.56x45mm NATO and .223 Remington ammunition.
All G2 rifles have a sub-MOA guarantee.
