Barrett brought their lightweight M240LW prototype to the Big Bang Shoot and SHOT Show. Unlike the M240L, which is in service with the Army, it does not use any exotic/expensive materials or manufacturing techniques to decrease weight. They instead decreased weight by trimming off as much metal as possible and decreased manufacturing costs by making the receiver in two pieces and then bolting it together. They managed to trim about 6 pounds off the standard M240B. Unfortunately Barrett ran out of 7.62mm ammunition before I had a chance to shoot it.
