The blue Maple Leaf Decepticons airsoft hop-up has a hardness degree of 70, making it compatible with airsoft guns firing between 360 to 460 FPS. These hop-ups are upgraded to keep the muzzle velocities stable while preventing air leaks, which cause inconsistencies and performance drops.
The company states that you should install these in Tokyo Marui/KJ gas blowback pistols and VSR-10 bolt action sniper rifles. The Decepticons hop-ups improve accuracy, making them excellent for precision weapons. You can also use them in older WE Tech gas blowback guns.
