Army Force P90 280 Round Magazine - Transparent is a polymer magazine for P90 Airsoft weapons. The magazine has plenty of space for BB's, allowing up to 280 to be stored. The spring mechanism is very efficient, meaning that when wound up fully will clear 90% of the BB's before having to be re-wound. Due to the construction of the magazine it is transparent, meaning you can visually see the amount of ammo you have left before entering a firefight. The magazine is designed for Tokyo Marui type magazine wells but may fit other manufacturers.
