ACETECH x 4UAD Hop-Up Bucking Nub for Airsoft GBB/AEG Inner Barrel 4UANTUM Friction Pro Compatible to BB up to 0.48 Grams

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!

• Designed for GBB Airsoft (Gas Blow Back), provides backspin to the BB as it enters the inner barrel, allowing the BB to travel further and with greater consistency.
