NOTE: DOES NOT WORK ON METAL FEED LIPS. We are releasing our brand new GHK M4 & G5 Odin speedloader adapter! (Also works with Odin rip offs) which makes loading GBB mags incredibly easy, fast, and painless. Doublestacks the magazines beautifully every time. Load your M4 & G5 mags in mere seconds. Does not come with Odin speedloader itself. This is only the adapter piece. - 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.
