New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Description:
The King Arms Colt M4A1 is the first 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. The King Arms Colt M4A1 uses a standard M4 Hand guard, LE Stock, and pistol grip making it perfect as it or a great base to build a tactical rifle. A M4 style carry handle with rear iron sight is included as well as a front triangle sight, both are adjustable for both elevation and windage so you can be sure your shots are straight and true. 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.

Product Information:
On a utility level, it's what you'd come to expect from an m4. Good fit in my hands, adjustable butt stock, two sling mounts, standard iron sights, top rail for optics/scopes, appropriate sized barrel. The blowback action is very enjoyable and quite a bit more intimidating than the usual rattling away of an AEG. Bothe the lower and upper receivers are metal, the barrel is metal, the handguard is dense plastic that i have had no issues with. butt stock is a bit flimsier plastic and will crack from multiple hard hits to it. The gun itself is very customizable as you can outfit it with a higher or lower pressure valve for more or less velocity. You can mess around with the buffer tube for higher or lower RoF. The hop up unit can be quite a bit inconvenient to get to however as it is within the hand guard and it can be a bit tough to take off (no screwdrivers or anything needed though.) All in all, its a damn fun gun to shoot and for the price, probably one of the more affordable higher quality GBBR's on the market.

Pros:
-Very customizable from the get go.
-Metal body
-Threaded outer barrel
-Comfortable size
-Good price
-Rail for optics
-Light weight
-Open bolt easy to fix jams

Cons:
-Pistol grip can get very uncomfortable from prolonged play
-Handguard makes it difficult to find a rail that will fit
-Magazines are very prone to damage causing your gas to leak
-Loading nozzle is plastic and can very easily break (the reason why I'm not using my rifle right now)
-Open bolt makes it undesirable to play in sand (I've done this, takes about 2-3 hours to fully clean)
-Butt stock material prone to breaking from falls
