Instead of using a standard receiver bedded inside a stock or chassis, the SIG Sauer CROSS rifle uses a single-piece aluminum receiver that bears similarities to the AR platform. The barrel attaches to the receiver using a barrel nut, allowing it to be free-floated and making it possible to get barrel-change kits in the future.
