The TF4 OPS from Tactical Force has all the features you're looking for at a great price. This CQB style AEG comes with a RIS Quad Rail Mount, tactical foregrip, detachable CQB rear sight, and a LE style retractable stock. The included magazine can hold up to 300 rounds of ammo. The rail system allows you to add tactical accessories such as lasers, flashlights, and foregrips. This is a CQB style gun, which means it has a shorter barrel than a standard carbine. This allows the user to maneuver more efficiently in close quarters environments. The gun does have an adjustable hop up which increases the range of the weapon. A rechargeable 7.2v battery and battery charger are included with this AEG. Features:
