The Colt M4 CQB-R AEG is a great two-tone desert tan and black airsoft M4 gun. Complete starter kit and quality OEM made by Cyma. Fully licensed Colt trademarks/logo M4 airsoft carbine with rails.Gun is primarily polymer built on the exterior with some metal components. The rail system, upper/lower body, furniture, stock sights, and buffer tube are all plastic. The outer barrel, sling attachments, magazine, and other moveable parts are metal. With the crane stock being plastic, we suggest not playing rough with it, or dropping it on the ground. There is no warranty on the buffer tube assembly due to mishandling. Otherwise, the gun is very solid and a great value! It shoots very well along with being reliable.
The Colt M4 has a metal quality gearbox, type version 2. It's rare to find a metal gearbox gun at this price.
Gun package includes a 8.4v 1100 Mah nun-chuck battery and trickle battery charger. Rear crane stock can fit a (sold separately) *9.6v 1600 battery (nun-chuck) too.
