Guarder Steel High Speed Gear Set for Airsoft AEG Gearboxes. (Ver.2 / Ver.3)

"these gears are great! i run these gears in my m249 with a m120. i also ran my m249 at 30ish rps and they did just amazing! the only problem i had with them is they where designed for marui type bushings so their gear shafts were to large for my bushing. but i sanded the shafts down till they fit perfectly.'


these gears dont fit non mauri type bushing( unless modified, and i am having some trouble with motor right now they keep burning brushes, i dont know if it is because of the gears or not)
