The service weapon of choice of the US military and others around the world is now available to you in this ultra-realistic incarnation. Brought to you by JG, the biggest name in airsoft, JG's long time experience in producing quality budget airsoft products have finally come together in creating this realistic and affordable option of M4 gas blowback guns. Utilizing pressurized as a power source, the entire design of this airsoft gun is more closely akin to how Real Steel firearms utilize combustion from gun powder to work. Specifically using green gas/propane as a power source oppose to NiMH batteries. Green gas can be injected into the MC6604's magazine via a nozzle located along the spine of the magazine. Done away are wires and connectors, charging batteries, and intricate gears and springs of the gearbox. What's left is a realistic shooting experience. Cock the gun by pull the charging handle back. Pull the trigger and feel a kick like no other type of airsoft gun could provide. The bolt will cycle with each shot, and lock to the rear once empty. Reload and tap the bolt release paddle to spring the bolt back into position and continue firing. As long as the magazine is filled with gas, that's all you need to lock and load - that's it!

With over 400 FPS power per shot the build of this gun features metal internal parts including bolt, charging handle, trigger pack, magazine, and barrel for maximum stability. Other parts such as the reciever are a new type of reinforced polymer not seen before in JG's guns but can handle the powerful pressurized gasses it will be using. Representing M4A1 Carbine configuration this rifle comes built with a triangle front post sight, removable Rail Accessory System (RAS) carry handle, classic polymer handguards, pistol grip, and LE stock.

2 of 5 Won't Hold Gas July 10, 2014
Reviewer: ebv from WA  
First, customer service with Hitguns was amazing.  They took care of my order and verified questions I had by phone.

Second, shipping was outstandingly fast.  I put most of the praise on the processing time.

Third, however, the magazine in this gun will not hold gas.  After a lot of fiddling with the charging handle, bolt catch and the little gas release doohickey on the magazine, we finally got it feeding.  And it shot great.  For a few shots.  We were using propane (with a couple drops of silicon oil in the hitguns-provided adapter), and the mag consistently ran out of gas before it was even spent.

The bolt catch also almost immediately stopped catching.  This is minor compared to the gas inefficiency of the magazine, which also just really wants to not accept gas.  It's too bad, too, because shooting this thing is a lot of fun.
