Airsoft Chay makes a list of the P90s in the market to find out which are the best for airsoft players. Brands in the list are CYMA, Krytac/EMG, King Arms, Tokyo Marui, and WE Airsoft. Missing in the list is the Classic Army version though it is probably out of production including the Sportline model. The WE version is the only gas blowback in the group.
