4UANTUM Friction Hop-Up Bucking for GBB/VSR 4UAD (4UAD FRC-PRO-GBB)

BRAND 4UAD

The 4UANTUM Friction Hop-Up Bucking is engineered by 4UAD to deliver maximum shot consistency for GBB and VSR platforms.

Its redesigned contact patch generates an extremely consistent spin on every BB, improving accuracy, trajectory stability and effective range.

While retaining a traditional single-point contact concept, the proprietary contour design creates sufficient friction to effectively lift heavy BBs up to 0.48 g.

The minimized contact area reduces alignment errors as the BB passes through the hop-up chamber, resulting in tighter groupings and improved shot-to-shot consistency.
