G&G is well known for their high quality internals, and their combat machine raider series is extremely popular. The Top Tech Series is G&G's line of high end AEGs. Top Tech's feature a full metal body, upgraded gearbox with low resistance 16 AWG Teflon wiring and 8mm ball bearing reinforced metal gearbox. They are 100% LiPO ready right out of the box. The Top Tech Raider L is an excellent choice for field play. It's lightweight, durable, and has a long barrel which is great for range and accuracy. Everything on the gun is fully made of metal except for the flash hider, pistol grip, and butt-stock. The grip more ergonomic than a standard M4 grip and is very comfortable to hold. It has molded finger grooves for a very secure grip. The crane stock houses the battery and the length can be adjusted for the user's preference. The metal body is very durable and has the G&G Top Tech logo engraved into the lower receiver, as well as a unique serial number. The rear sight is full metal and adjustable for windage and elevation. It can easily be removed to reveal a full length picatinny rail which can be used for mounting optics. The gun comes with two rail covers that can be used for covering any unused rail space. A tactical G&G foregrip is also included for a more secure grip on the weapon. For best performance, we recommend a 9.6v NiMH battery with this AEG.
