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 Madbull Daniel Defense Light which is one of the most high quality rail systems we carry. The Madbull Daniel Defense is a fully licensed one piece free float rail system that is constructed completely out of a high grade aluminum 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.

Product Information:
I purchased the King arms gbb rifle with the aluminum rail system about 6 months ago or so. I hadnt had time to get out and play with it for the first couple month because i was reay busy. i finally got out to use it and i was extremely happy how the gun felt and how much realistic kick the gun had to it let alone the was the bolt actually operates like the real thing. After shooting for about 10 minutes i loaded up another set of mags and knowing of the recall on these guns(cant load mag past 50 rounds or the loading nozzle will get damaged) knowing this i always made sure that loaded exactly 50 in and for good mease i always took out two bbs after done loading. after bout a half of magazine woth of shots the rifle started dry firing. so i check the nozzle and sure enough it was damaged just like they said. So i took the blame thinking that i must have loaded one of the mags to much. I bought a new replacement nozzle and installed that and about a mag and a half in it started to dry fire again. and this time i no that loaded less than 50 round i wasnt going to make that $70 (thats how much the replacement part was) mistake again. So all in all i love the look and feel of this gun soooo much but for this to happen twice and even when i loaded the mag with less than 50 rounds.... i really was not happy especially for the price i payed for this gun.

-Great look and feel
-shoots great(when it shoots)

-Loading nozzle get damaged even when u load less than 50 rounds in!
-Replacement part costs $70!
-barrel was very wobbly when it came

Product Information:
I purchased this gun last summer and it took a couple weeks for Airsoft GI to build it but it was well worth the wait. It operates just like a real m4, extremely sturdy, shoots straight, and no wobble at all. I am very pleased with the Daniel Defense rail system that was put on. All in the gun was well worth the money and if I was you I would purchase this gun the next time itÂ’s in stock.

Extremely sturdy
Speed buffer to allow fps to change
Very versatile
Operates like a real m4
Disassembles like a real m4 too

Mags are a bit more if you are upgrading from an AEG (not necessarily a big problem)
To take the pistol grip off you have to use a torque screwdriver (T25 I believe) to change the pistol grip (not really a problem just an inconvenience)
No serious problems
what kind of mag do i need to buy so i can have more than one
i would like to have more than one mag
