This hop-up bucking from Maple Leaf has a hardness of 70 degrees and comes in blue. Its one of several buckings offered by the company. The device ensures your airsoft guns propel BBs at consistent flight paths and velocities.
The bucking will fit Tokyo Marui/KJ gas blowback pistols and VSR-10 bolt-action airsoft rifles. You can also install them in older WE-Tech gas blowback guns for improved performance.
