The King Arms Colt M4A1 is the first M4 style GBBR that has been approved for sale in America by the ATF. The King Arms Colt M4 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 Techs here at Airsoft GI took this already amazing gun and added the G&P RAS 2 Kit which is one of the most high quality rail systems we carry. The G&P RAS 2 kit features an extended rail that bridges the gap to the top of the receiver. This rail not only gives the RAS II a more secure fit, it allows optics to be mounted higher up to aid with aiming. The G&P RAS 2 is a very solid rail system and makes the King Arms M4 look amazing. The King Arms Colt M4A1 uses a LE Stock, and pistol grip making it perfect as it or a great base to build a tactical rifle. The King Arms M4A1 features a 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 M4A1 is like none other. The bolt of the King Arms M4 is extremely smooth and provides for a very crisp and reactive shot. The recoil of this M4 feels very realistic and definitely increases the realism factor of your airsoft play. The King Arms M4 is truly the first affordable and high quality GBB M4 that is currently on the market and is a great gun for anybody looking to get into Gas Blow Back Rifles.

Anyone like myself who finds themselves in the realm where the airsoft and firearms communities overlap are familiar with the debate over the viability of airsoft guns for firearms training. It goes back a long time. I have used gas blowback pistols for training many years. The cost of operating an airsoft gun, although not inexpensive, is like night and day when compared to a real firearm. For that reason alone I am a proponent of using airsoft for training. It comes with limitations but it is one more tool for the tool box.
And, more recently airsoft has been gaining momentum in the firearm community as a viable training tool, especially as ammo prices have soared. Travis Haley of Haley Strategic Partners, well established in the firearm community, has endorsed airsoft guns as a means for training in a recent video and does an excellent job of explaining the advantages.
I remember getting the occasional law enforcement orders years back for gas blowback pistols because functionally they were quite similar to their real firearm counterparts but the demand was never that great for rifles and I feel one of the primary reasons was the dominance of AEGs on the market. At the time although useable for force on force training they had several shortcomings such as being dimensionally different then real firearms since they need to house a gearbox, motor, and battery. I will not detail all the shortcomings as that would take an inordinate amount of your time and mine.
Developments like the Systema PTW and others fixed some of the problems. For example, the Systema PTW used a new motor and gearbox design that aside from being more efficient enabled the PTW to have a proportionally correct size pistol grip and receiver. Also, the Systema PTW design had a functional "bolt release." I emphasize bolt release because that is what it was meant to simulate, the release of the bolt carrier group to chamber the first round after inserting a new magazine. But in reality the Systema PTW did not have a bolt at all.
That was the shortcoming of the PTW and similar systems; the lack of a bolt carrier group. As a result the charging handle and forward assist did not function. Since the release of the PTW there have been blowback AEGs but that normally consists of a thin metal plate "recoiling" back. Aside from that they are not functionally different from conventional AEGs.
Enter the gas blowback rifle. Over about the last 2 years the airsoft market has seen the emergence of gas blowback rifles. Although gas rifles have been around many years they have been outshined by AEGs but models like the King Arms gas blowback M4 and others have addressed the shortcomings of AEGs, at least in the training sense. The design of such gas blowback rifles bring airsoft guns to a new level as training tools. Like the Systema PTW they are dimensionally similar if not that same as their real firearm counterparts.
The difference comes down to the internal operation. There is not an electrical switch. When you pull the trigger a hammer is released, a bolt carrier group recoils/blowsback; into a buffer tube that has a buffer and spring. As a result the trigger feel, fieldstrip/breakdown, controls, felt recoil are all more realistic. Every sensation and operation is enhanced. The near future release of KWA's gas blowback M4, the LM4, gives me further hope for the future of the gas blowback airsoft rifle as a training tool. KWA promises it will out perform and provide greater efficiency then current platforms.
The only significant shortcomings from my perspective remaining with the gas blowback rifles is they function less efficiently in cold and no marking ability. I discount the decreased accuracy as compared to a real firearm out of hand as my primary concern as a training tool is for force on force scenarios and weapons manipulation practice. In regards to the remaining shortcomings we are light years ahead of where we were a couple years ago. I was there, I remember. The desire is always to have the perfect system but in this world nothing is perfect so for the time being such shortcomings can be worked around and should not deprive us of a viable training tool.
