Wyhaq got the LayLax Nine Ball Hi Capa HPA/M4 Magazine Adapter and shows how to install it for a quick review... "In this video, I show how to install the newest hpa adapter from LayLax Nine Ball. This is an injection molded m4 magazine adapter for HPA systems. This is a very competitive option, at a significantly lower price than the other options on the market. This is a great choice for speedsofters or just normal airsofters that like cool stuff. This adapter carries over the same design style that Laylax uses on their other hi-capa upgrade parts."
