The Clover Airsoft Odin M12 Upgrade Gear is an absolute game changer for you Odin’s and other Side-Winder style clones. Not only does this increase the durability of your loader, but it will let you fully load even the strongest mid caps with ZERO break on (I’m looking at you EPM1’s!) We are so confident in this product that we include a 1 year warranty! The upgrade gear is easy to install, all you need is a Phillips head screw driver and an adjustable wrench. Speed loader, obviously, sold separately!
