TSD-Tactical AK47S AEG Generation II- Ultra high torque motor- 3 pieces steel gears- 600 round magazine- metal gearbox- metal bushings- metal hop-up unit- metal folding stock. Real wood pistol grip- upper & lower handguards- 330-350 fps with 0.20g BB's.
Hop-up's main function is to increase the range of the BBs travel, making for longer shots. However, not all airsoft guns have a hop-up mechanism (check the make and model of your gun). Adjust your hop up lever to make it spin more or less. The hop-up mechanism on an airsoft gun imparts backspin on the BB. An adjustable piece of rubber provides resistance on the upper part of the BB when fired, causing backspin. The backspin creates a counteraction for gravity allowing the bb to shoot farther.
