Golden Eagle Airsoft Full Metal M4 AEG Upper / Lower Receiver Set
The Golden Eagle Airsoft M4 AEG Upper and Lower Receiver Kit is a perfect and affordable option for building a custom AEG from scratch! It’s also best suited for upgrading standard M4 receivers to a full metal build for maximum durability. Aside from the upper and lower receiver, this complete airsoft M4 receiver kit comes with everything you need: body pins, dust cover, charging handle, mock bolt catch/release, safety selector switch, and magazine release button. Additionally, a flat top receiver rail lets you mount a variety of sights, red dot scopes, and other sighting systems (even an aftermarket carry handle).
