The Commando model features an 11-1/2 inches lightweight "A1 inches profile barrel with a 1:7 twist rate, integrated into a C7 upper receiver equipped with a shell deflector and CAR handguards. This model represents a unique fusion of traditional and contemporary design elements, bridging the gap between the M16A1 and the modern M4 platform. The 733 C7 configuration incorporates sufficient modern features to serve as a reliable setup, particularly for users who prefer a carry handle receiver. The A1 rear sight, housed within the C7 upper receiver is renowned for its robustness and reliability. Originally exclusive to Canadian AR-15 models, the C7 upper combines elements of the M16A1 and M16A2, essentially functioning as an M16A1 receiver with the "Burton bump" shell deflector from the M16A2, a feature now standard on modern forged uppers. The barrel, measuring 11-1/2 inches, is chambered for 5.56x45mm and features a 1:7 twist, offering a distinctive carry handle configuration with a tighter twist rate. It includes a chrome-lined bore and chamber with a phosphate exterior finish, enhancing its lightweight and maneuverability. The barrel is finished with an A1 flash hider. The accompanying Bolt carrier group adheres to standard military specifications, featuring a phosphate-coated exterior and a chrome-lined interior carrier and gas key.
