Technical bucking engineered to increase flight stability and repeatability on VSR platforms and many GBB units. The advanced profile enlarges the BB contact area to promote consistent backspin; the silicone compound keeps elasticity at lower temperatures and offers good wear resistance. Recommended for users seeking predictable trajectories on tuned replicas without structural modifications.

Technical specifications

Type: hop-up bucking for airsoft replicas.

Hardness: 50° (soft — suited for certain FPS ranges and setups).

Material: high-elasticity silicone.

Design: wide contact patch for consistent spin; geometry compatible with VSR-spec inner barrels and many GBB hop-up units (verify fit with your barrel).

Compatibility: VSR-10 spec inner barrels and various GBBs using the VSR-style hop-up.

Package contents: 1 × MR Hop-Up 50° bucking (Maple Leaf).

Vendor reference: 7160 (verify SKU/variant with supplier).

End-user benefit
Improves shot-to-shot consistency and maximizes the effective range and grouping of tuned replicas, especially when using heavier BBs or specific tuning setups.

Warnings & safety information

Keep out of reach of children.

For airsoft replica use only; not for firearms.

Do not tamper with the part: drilling, cutting or unapproved adaptations void warranty and may endanger reliability and safety.

Avoid prolonged exposure to direct heat, solvents or chemicals that could degrade the silicone.

Store dry at room temperature.

Dispose of according to local regulations for rubber/silicone.

After installation perform controlled test shots in a safe area to confirm correct fit and hop-up adjustment.

Usage instructions

Remove existing bucking and thoroughly clean hop-up chamber and inner barrel.

Fit the bucking ensuring correct lip orientation and alignment with the inner barrel.

Reassemble the hop-up unit carefully and perform test shots to dial-in settings for your operating FPS.

Do not force the lip with improper tools; handle with care.
