Full description


NUPROL - Dominate The Field Banner

These Airsoft magazines are ideal for those that prefer mid-caps over the rattle of high capacity magazines and can see themselves wanting to take part in 'MilSim' or Military Simulation events where you need to carry realistic capacity magazines - rather than investing in a load of specialist magazines you can use these mags to cover both bases. The magazine consists of a tough Polymer external shell that has ridges and textured grip panels to improve handling of the mags and also make them look extremely attractive, especially for those of you with modern era equipment. To switch between the different BB capacities, simply remove the base plate and the internal section of the magazine to reveal the switch. From here you can also quickly and easily remove the entire spring from the mid-cap by removing the cut out section. This is fantastic for when your mags start to age or you use a low quality BB which jams inside the follower, as normally any jams would be a pain to remove in a mid-cap magazine. 

Due to it's medium capacity design, holding up to 125 rounds and being spring fed, it will not rattle unlike it's High Capacity counterpart. Rather than the hundreds of rounds found in High Cap Magazines, this magazine adds a slight element of realism as it forces users to conserve their ammunition and limit their trigger usage. As this is a mid cap design, ammunition can be loaded directly into the top of the magazine using an Airsoft speed loader. 

Whether you want to rid yourself of high cap rattle (the shaking noise made when you run around with high capacity magazines), have the option to take part in realistic Airsoft events or just own modern era kit that you want to add extra bling to, these magazines are perfect.
