The King Arms Colt Full Metal M4 MRE Gas Blowback Carbine Airsoft Gun is fully licensed by Cybergun and sports amazingly realistic Colt trade marks on left side of the receiver. The receiver of this gun sports a perfect finish that nearly mirrors that of the real steel rifle. So you don't have to worry about fitment or installation the awesome staff at King Arms have added a 12 inch free-floating FFS RIS system that is constructed completely out of a high grade aluminum that not only makes the King Arms M4 look amazing, but also provides a strong tactical advantage by providing the ability to add lights, lasers, grips, and other accessories.The King Arms Colt Full Metal M4 MRE features an adjustable rate of fire, the rate of fire is easily adjusted by simply removing or adding the spring buffers. Also featured on this gun is a adjustable FPS, included with this gun are two valve blockers. One valve blocker is designed for high FPS with the other is for lower FPS. Shooting the King Arms M4 is like none other. The bolt of the King Arms M4 is extremely smooth and provides for a very crisp and reactive shot.

    Product Information:
    This is my first GBB gun and I was amazed by it. The kick on it is nice, its a realistic weight, the full metal is very durable and the sound of it strikes fear into the hearts of my enemies. The only weird thing about it once I got the gun was the front sight. It was loose and the screws that keep it in place were missing but that didn't bother me to much because I ended up taking the sights off and replacing it with my red dot that I had for my other M4. However the magazine on this thing might as well be a paper weight. The gas never holds and ever now and then once I go to fire it there will be no gas after I just filled it up which can be very frustrating once you're hiding and want to take someone out. Expect to get new mags once buying this gun
