Full description


This magazine is mid-capacity, meaning that the BBs are fed by a spring to the weapon and there is no need for clockwork wheels or winding; simply insert the magazine and fire through the rounds until it is empty. These types of magazines are ideal for indoors play where you're limited to single shot, as you will definitely know when a magazine is empty whereas high-caps sometimes need winding and that few seconds of confusion can mean a walk to the safe zone. These magazines are equally suited for outdoors players who either don't like the tell-tale rattle of high-cap magazines or prefer a more realistic style of play. (It's also ok if you just like to throw in tactical reloads where possible).  Being constructed from Steel, these magazines are incredibly tough and have a fair amount of weight to them, which will help make your weapon feel extra solid in the hands. On top of all this they should be compatible with 95% of M4 based Airsoft guns, as CYMA magazines are highly compatible.
