This is the M74 assault weapon. Developed during the war, in about 2025, near as we could tell, it is by far the most advanced infantry weapon ever made. The weapon itself is incredibly impressive, but it is the platform that really makes it incredible. It fires a .202 caliber round that has a small bundle of titanium flechettes imbedded in soft lead and jacketed in a copper alloy. While the caliber sounds small, the Muzzle velocity is fifty eight hundred feet per second, which gives it more kinetic energy than the rounds you fired with your M1.” He handed Jack one of the rounds. It looked like just a bullet, not an entire round. “When the round hits a target, the lead mushrooms like the ammo you are used to, but the flechettes spread out and continue on, tearing through just about any kind of armor you can imagine. Soft targets just cause the flechettes to sprawl through the body and cause maximum damage. The ammunition magazine holds two hundred rounds and weighs less than the twenty round magazine of the M14. The casing is only three quarters of an inch long and the entire round is a little over an inch. It uses a chemical that burns eight times faster than gunpowder and expands over fifteen times more. The reason the round is so small is because the chemical propellant is solid and doesn’t need a shell. It is completely consumed when firing, so nothing to eject. The gun uses a hybrid closed bolt system that completely contains the explosion, routing the excess energy to power the action, and even to help counter the recoil.” “Fifty eight hundred feet per second? Even a bullet that small needs a heck of a lot of energy to get moving that fast. This thing must kick like a mule.” “Actually, the action on the weapon uses a shock absorber filled with a magnetic fluid that changes viscosity depending on what the fire rate is set to. If you fire a single round, it softens up to make recoil almost nonexistent. If you go automatic, it stiffens up to increase the cyclic rate. The weapon itself is made of composite carbon fiber and titanium alloys, with a frictionless surface in the barrel and on all moving components. It’s a bitch to clean because each piece is like wet ice, but it almost never needs cleaning because nothing will stick to any part that matters.” He
