MR. Hop Up 85° Silicone for VSR & GBB

MapleLeaf Hop-Up bucking for GBB guns and sniper rifles. A metal ring is part of the package, which increases the sealing even more after being put on the bucking. However, its use is not a condition.

Bucking MR HOP "Maximum Range" can be used without modifications for gas GBB guns and the VSR10 series. A larger and wider contact area causes a better HopUp effect even with heavy balls. Designed for heavy bullets only.

This is a new improved version made of silicone which can better withstand colder weather.

Before buying, make sure that the hardness of the bucking suits power of your gun - see below.

• 50° for guns with the output velocity bellow 110 m/s (360 FPS)
• 60° for guns with the output velocity 90 - 120m/s (295 - 400 FPS)
• 70° for guns with the output velocity 110 - 140 m/s (360 - 460 FPS)
• 75° for guns with the output velocity 130 - 150 m/s (430 - 500 FPS)
• 80° for guns with the output velocity above 150 m/s (500 FPS)

Notice
For the hop-up bucking to function properly, the used barrel must not have a bridge at the pressure hole.
