    Our take:  This factory original spare King Arms Colt M4 Gas Blowback Rifle spare magazine is manufactured by GHK, and is compatible with all GHK GBB Kit equipped M4 airsoft gas blowback rifles. This spare King Arms GBB Colt M4 magazine can use HFC134a gas (low pressure gas), green gas, or propane with silicone oil. The magazine has a large gas reservoir capable of holding more than enough gas to empty your entire magazine. The magazine has a 40 round capacity, which is perfect for most MilSim airsoft games. This magazine is constructed entirely of high grade metal and has a reinforced nozzle and magazine feeding lip. This is a must have if you are using the King Arms Colt M4 GHK GBB Kit Gas Blowback Rifle!

    Note:  Filling the magazine OVER 40 rounds can damage your airsoft GBB rifle.

    "Do not overload these mags or load to 40. Loading past 30 will put too much upward stress stopping the bolt from moving back forward all the way. It also shoots multiple BB's at once when loaded close to 40. This is my experience with the GHK kit in a G&P Body. I modded the body to change around pressure on the GB and alleviate some else where and it is better, but still shoots too many BB's overloaded. After a few games. NOTE: I play very hard. 5 out of my 8 mags work great. 1 fails to hold any gas. The other leaks at such a rate that it only holds gas for 1 minute. The other leaks a little slower and can last 5 minutes. I learned after the game I was suppose to keep gas in mags when i store them. I did not. I also didn't know you were not suppose to release all the gas at once pressing the nob. I did that. So this may be my fault. Eitherway, In the end 5 out of 8 mags are usable. Will have my friend who works on GBB repair them. All mags have problems loaded past 30 with a GHK in a G&P Body. So honestly at this rate its a 2.5 stars. I rated 4 for one reason. In the cold WITH on a fully filled mag I can go through 5 reloads of BB's before refilling gas... NO. OTHER. MAG. can do that."

    "I bought the gun that came with the GHK M4 Gas Magazine. When I loaded the Mag, the bbs got jammed every time it got loaded. I told my self, well that's probably a faulty mag that came from manufacture. So I went and bought a second one. Same magazine. Spent $71 with shipping. Major damage to my wallet and budget. When it finally arrived, I loaded it up and it also got jammed, at the same spot where the first mag got jammed. It's not coincidence!!! These mags SUCKS. They Get jammed and I'm not wasting $71 for another "faulty" magazine.!!!!! DO NOT BUY"
