The G5-A5 was put together primarily for the long range of Field/MilSim play. This series of mid length carbines are packaged with a 16 inch outer barrel and a URX style RIS unit. These two significant parts increase the range, accuracy and looks without sacrificing functionality. The rail space provides plenty of room to accompany a bipod and long range scope. This is the perfect for the weapon for engaging Opfor within 100 to 150 feet.
