The Airsoft GI G4-A3 Version 2 Carbine is a great new update to the G4 line up of custom guns from Airsoft GI. The base gun is a special Combat Machine M4 Blowback with a crane stock that\'s wired to the back. This is apart of a new line up of guns to be manufactured by Airsoft GI. We\'ve worked out a special program with Combat Machine to build us a special pneumatic blowback M4 with a crane stock, sling mount, and the wires to the back, so we can eliminate the need for a PEQ box and keep a clean look. The Combat Machine was carefully chosen for their high quality, reliability and incredible value. We\'ve dropped the G4 straight onto the ground from 8ft and 9ft with no visible damage to the body; this is the strongest plastic receiver on the market. This version of the G4-A3 has been updated with a new and improved motor from G&G. This motor performs significantly better and is also much more durable then the version 1 motor. The rail of the G4-A3 has also been updated with the G4 7\" free float ris which is paired with a gas block style flip up front sight. The G4 7\" free float RIS is a great addition to this AEG and features an extremely high build quality as well as compatibly with nearly any picatinny rail accessories. The Airsoft GI G4-A3 Version 2 Carbine with its new and improved features took the already renowned G4 and made it even better. The G4-A3 version 2 carbine is sure to impress any caliber of player with its amazing value and performance.
