About the M4 High Cap Magazine
This is a high capacity magazine for your M4 style electric airsoft gun. It fits in just about every M4 ever made. These magazines are made of metal and should feed about 100 rounds on a full wind. These are tested to work with just about all of the M4 style guns we carry including: Elite Force, VFC, Classic Army, Echo1, ICS, Lancer Tactical, ASG, Apex, and more.
How to use a high cap magazine
High cap magazines are identified by the trapdoor, usually found at the top of the magazine and a winding wheel on the bottom. The magazine is hollow inside so you would open the trapdoor and pour the BBs into the magazine until it is full, all the way to the top. Shut the trap door and begin winding the magazine. High cap magazines require that you wind the wheel on the magazine before use, otherwise the magazine will not do anything. You will turn the wheel on the bottom of the magazine for quite a few turns. As you turn it, it will make clicking sounds. You will want to do this until the internal spring in the magazine is at its maximum tension. When it reaches its maximum tension, turning the wheel will make a different type of clicking sound. It will be noticeably different and that is the sound of the internal mechanism letting the wheel slip as not to overwind and break the internal spring. On a full wind, you should be able to fire off about a third of the magazine (in the case of M4 magazines) before you need to wind again.
High caps vs. mid caps
Players who want outright capacity should go straight to high caps. You do not need to carry as many to have plenty of ammo and the cost for all these magazines will not be as much as carrying a full complement of mid caps. The downside to high caps if you didn't already know is that they are noisy especially while moving. Fully loaded high caps won't make much if any noise but once you start using it, the magazine will have a lot of space for BBs to bounce around. We often joke and say they sound like a baby rattle. If your play style keeps you stationary a lot then it probably is not a big deal. The required winding of the magazine may also be considered a turnoff to high capacity magazines.
Now for milsim minded players who want something more grab and go, the mid cap is the better solution. They do not make noise and provide a bit more excitement due to more frequent reloads. Mid caps are straight forward in their function and all you do is insert the magazine and go. No winding is required. Some events might restrict you to the use of mid cap magazines (many major milsim ops) for the sake of keeping you immersed and conservative with your ammo.
