R-Hop Patches Set
The set contains 8 patches, 4x2 types with different depths sizes.
Mounting a R-Hop patch will improve the range of the rifle.
The patches are made of flexible silicone, which ensures sealing and at the same time gives a suitable effect to the bbs.
The R-Hop patch provides a much larger contact surface with the bb, resulting in a better rotation effect.
Can be mounted on most AEG and sniper barrels.

If you choose to mount a patch, you must choose a suitable hop-up bucking and a suitable "omega" type Nub, that will be centered for better control of the hop up system.
Depending on the barrel on which the R-Hop patch is mounted, adjustments of its shape and dimensions may be needed, but the patch has the right thickness, so no sanding the surface will be required.
