We are releasing our brand new WE M4 GBB Odin speedloader adapter! (Also works with Odin rip offs) which makes loading GBB mags painless. Loads the magazines beautifully every time. Load your WE M4 GBB magazines much easier. Loads all 31 rounds of STANAG WE M4 magazines. 👉IMPORTANT NOTE: GBB magazines require more torque on the Odin crank handle to fully load. The best practice is to crank slower but firmer. Please be aware of this and don't be surprised when it requires more force to load. You have been warned. - Custom colors available upon request (Depending on what we have on hand at the time. We have many colors.) - Made out of heat resistant ABS. Won't melt or deform in the car. If you have any other questions please ask.
