4:54 no! The M4 is a carbine, it has a shorter barrel and is lighter and better suited for CQB (doubt you know what that is) while the M16 is longer and has better range and accuracy but is not good at CQB stop pretending you know about guns because obviously you don’t
Man i make realistic load outs and a rifle and pistol is not a loadout, for America I usually do M4, Remington shotgun, M17, 2x frags, flashes and Medkits then A10 strike
