Loading gas blowback magazines is a hassle. The magazines are difficult to load and the options for loading these types of magazines are limited. As someone who runs GBBR, this issue nearly made me return to electric airsoft rifles. 

I designed this speedloader exclusively for M4 magazines made by WE-Tech. All you do is tip the loader over to get BBs into the channel and push down on the green pushrod to load the 30rds into the magazine. You can load your 8 magazines in under a minute with this tool. It was designed to be an overkill solution.
