Beskrivning

Hopup rubber to fit GBB guns and VSR barrels.

A+ Airsoft rubbers are made of high quality silicone rubber, the rounded shape of the contact surface allows the rubber to make better contact with the ball
giving it a better and more stable spin and ball trajectory.

If you compare this rubber with an original rubber, you will see a big improvement in the accuracy and range of your pistol or rifle.
For optimal results, you need to use either a concave nub/tensioner or a flat nub/tensioner so that the contact surface retains its round shape when pressure is applied.
