For: G&G Hyper-Torque Gear Set (Helical)Product Information:
This set of gears is great! i have them running an airsoft surgeon stage 5 spring and they can push it at a good rate. i have put over 5000 rounds through my semi auto sniper and have checked the gears for any unusual wear marks, none whatsoever! these things are great and at a very good price.
easy to shim for helical gears
can handle strong springs with a good rate of fire
less expensive than most gears
