Lancer Tactical AEGs are high quality and affordable. Features include a full metal version 2 gearbox and durable polymer construction. The polymer body keeps the weight of the gun down while the metal gearbox provides the power needed to dominate on the field. These AEGs are ready to roll right out of the box! A 300 round high capacity magazine, 9.6v battery, and smart battery charger are included. The Lancer LT-15 M4 SD clocks in at 370-390 FPS making this an excellent all around airsoft rifle. Other generation 2 upgrades include a quick-change spring gearbox and 6.03mm tightbore inner barrel for added accuracy.
