2021 Transformers Autobot 70 is a hop-up rubber made of a mixture of silicone, designed for the VSR and GBB series replicas.
Its secret lies in the innovative shape of the element that wind the balls - DELTA. It is thanks to this unique shape that the accuracy of the shots is significantly improved.
The silicone from which it is made is very resistant to low temperatures, without the Cold-Bore Shot effect - it does not require "warming up" to obtain a stable ball flight path and full range.
Works great in sniper rifles.
Thanks to the larger and wider surface of the ball style, it provides optimal curl - perfect for heavy balls.
Before buying, make sure that the hop-up rubber will fit your barrel.
