MR. Hop Up 60° Silicone for AEG guns

Hop Up bucking "Maximum Range" for AEG, designed for longer range. The larger shield-shaped contact area inside the bucking ensures a better hop-up effect, especially with heavier BBs.
This is a new improved version made of silicone which is better able to withstand colder weather.

Choose the hardness of the bucking according to the power of your gun:

• 50° for weapons with a muzzle velocity below 110 m/s (360 FPS)
• 60° for weapons with a muzzle velocity of 90 - 120 m/s (295 - 400 FPS)
• 70° for weapons with a muzzle velocity of 110 - 140 m/s (360 - 460 FPS)
• 75° for weapons with a muzzle velocity of 130 - 150 m/s (430 - 500 FPS)
• 80° for weapons with a muzzle velocity above 150 m/s (500 FPS)
