Angus "Custom Spring for Next-Gen AEGs (Strong)" - This part is for advanced users.
110% compared to Marui's genuine spring (The airsoft gun used for spring comparison was the Tokyo Marui Next-Gen AEG URG-I.)
The custom specification example was confirmed using a barrel length of 247mm, a barrel inner diameter of Φ 6.05mm, and other custom parts.
For installation, the side of the spring with wider spacing faces the piston.
If installed in an airsoft gun with a genuine barrel length, the legal muzzle velocity may be exceeded.
It is the customizer's responsibility to strictly adhere to the muzzle velocity regulations of the revised Firearm and Sword Control Law. Please customize in compliance with the law.
