Element 1 - Hop-Up Chamber and Barrel
Firing Mechanism - Hop-Up.
Hop-Up back-spin airsoft BB's to increase their range. Hop-up acts somewhat like the rifling on the barrel of a firearm.
You can adjust the power of back-spin. Using high pressure about 10bars (145PSI) provides high rate of fire. Firing mechanism is designed to over 10,000 RMP. The longer barrel provides greater accuracy and power. Depending on the pressure the BBs can gain power more than 3 Joule.
