The G&G M4 GC16 MOD0 A1 AEG, in black color, is a great all around option for airsoft.
This is a very limited edition release! Includes a rare full metal body for its price point. It features a removable flip-up rear sight, removable front sight, top rail, 6 position adjustable rear stock, and a handguard with modular rail slots (3 rail sections included). The rifle is very ergonomic and comfortable to hold. The stock features a storage compartment capable of holding at least 1 18650 battery or at least 2 CR123 batteries. Unlike the other rifles in the CM16 series, the MOD0's charging handle does pull back a fake bolt. If you're looking for a value priced full metal body AEG, this is about as good as it gets! This is the high velocity model. This is also a close variation to the sold-out 30th Anniversary Edition.
Note: Does not include battery or charger (uses 9.6v 1600 nun-chuck style battery and smart charger)
