WE - MSK ACR AEG - Tan is WE's take on the Adaptive Combat Rifle (ACR) created in the United States. The Airsoft weapon itself has a polymer lower reciever and stock, with an alloy upper and hand guard. The gun comes with a M90 spring installed providing a high rate of fire, but can be upgraded to have more power at the cost of speed. Designed with a 14mm CCW thread this rifle can be fitted with an Airsoft Supressor or Tracer unit. The front rail comes with 3 movable rail mounts allowing you to adjust the rifle to fit flashlights and lazers. This is the perfect gun for left handed shooters as the rifle is fully ambidextrous, with ambidextrous magazine release, bolt release and fire selector.
