Hop-Up AEG Bucking 4UANTUM Friction Pro - High Performance

The 4UANTUM Friction PRO hop-up bucking by 4UAD is a high-performance upgrade designed for airsoft players who demand enhanced precision and shooting consistency. With its innovative contact patch shape and premium materials, this bucking is an excellent choice for players who want accurate, stable, and repeatable shots even when using heavier BBs.

Hop-up buckings affect BB backspin and flight trajectory. This model focuses on perfectly centered spin and minimizing flight irregularities common with standard buckings. Its contact surface provides sufficient friction to lift BBs up to 0.48 g, while maintaining minimal surface contact – resulting in fewer inconsistencies and higher shot repeatability.

With a hardness of 70°, the bucking strikes a great balance between flexibility and sealing. It delivers excellent air seal and wear resistance, even during intensive play. You can rely on its long-term performance without frequent replacements or tuning.

The 4UANTUM Friction PRO is compatible with most AEG replicas, including M4, AK, and other common models. Installation is simple and beginner-friendly, making this upgrade accessible to players of all experience levels.

Included in the package is a 4UAD nub, carefully designed to work in synergy with the bucking for even better hop-up performance. It ensures even pressure distribution on the BB, contributing to consistent range and trajectory.

This bucking also delivers great efficiency with heavier ammo in the 0.25 g to 0.28 g range, commonly used for accurate mid-to-long-range shooting. You'll notice a significant improvement in both range and grouping, which is critical in tactical gameplay.

Whether you play urban, woodland, or CQB games, the 4UANTUM Friction PRO will give you better accuracy, longer range, and more reliable shooting performance – all without sacrificing durability or consistency in harsh conditions.
