XM8 and related rifle seen in Homefront, the XM10 wouldn't be in the game. SCAR-L and SAR 21 seem to have low recoil because of low rate of fire. SCAR's rate of fire is 625 rpm while the SAR 21 is 450-650 rpm (actually considered 600 rpm). They considered the accurate and low recoil 5.56 assault rifles and should be in MW3. 600 rpm --> Low recoil. 1000 rpm --> High recoil.
