The hop-up rubber MAPLE LEAF "MACARON" type has been specially designed to significantly improve the accuracy of shots.
The secret lies in the innovative shape of the element that is making spin for bb - "DELTA". It is thanks to this unique shape and the use of an Omega type spacer. The accuracy of shots increases significantly.
The air seal rings on the outer surface provide additional sealing and prevent the rubber from moving inside the chamber.
The 60 ° hop-up rubber is recommended for 300~ 390fps replicas.
