Product Description

Features

  • High quality rubber construction
  • Designed to create perfectly centered axis of spin for ultimate consistency
  • Unique contour of the contact patch allows the lift of heavier BBs up to 0.48g
  • Minimized contact surface to eliminate error
  • Flat, consistent and accurate trajectory!
  • Improve accuracy, range, and groupings
Designed to achieve ultimate consistency, the Friction Pro hop-up bucking focuses on creating a perfectly centered axis of spin in every shot. While based on a rather traditional single-point design, the unique contour of the contact patch generates enough friction to even lift heavy BBs up to 0.48 grams, while minimizing contact surface to ensure there's no room for error. Resulting in a flat, consistent, and accurate trajectory!

"Although I didn't buy it from here. I must say this hopup rubber is great! It allowed my vfc g36c v2 gbbr that I recently converted into a full size version to shoot laser straight using the poseidon 470mm inner barrel combined with this. It definitely beats other rubbers to dust!

"I have used this bucking on 3 of my airsoft guns and have been pleased with the results. I highly recommend this bucking.
It is becoming my go to bucking when thinking of upgrading.
