The Transformers Autobot 70° bucking by Maple Leaf is engineered to improve air sealing and shot-to-shot consistency on VSR platforms and on many GBB pistols/rifles. Its pressure-point geometry and C-Clip reinforced lip stabilize the bucking’s contact area, reducing variability and yielding more predictable trajectories under higher velocity setups. The material formulation provides elasticity and durability suitable for tuned replicas.

End-user benefit
Improved air seal and more consistent muzzle behaviour translate into better effective range and tighter, more predictable shot groups on tuned replicas.

Warnings & safety information

Keep out of reach of children.

Intended for airsoft replicas only; do not use on firearms.

Do not use to look directly at bright light sources (such as the sun, lasers, or intense lights), risk of eye damage.

Do not tamper with the product: opening, modifying or DIY adaptations void warranty and may compromise safety and function.

Avoid prolonged exposure to direct heat, aggressive solvents or chemicals that can degrade the material.

Dispose of in accordance with local rules for rubber/silicone components.

Usage instructions

Remove the old bucking and thoroughly clean the hop-up chamber and inner barrel before fitting the new bucking.

Install the bucking ensuring correct lip orientation and seat any C-Clip into its groove if required.

Check inner barrel alignment and reassemble the hop-up unit carefully.

Perform controlled test shots to adjust hop-up settings to your replica’s operating FPS (70° recommended for mid-high FPS).

Do not force or damage the lip with improper tools during installation.

Tampering prohibition
Do not alter, drill or adapt the component in ways not intended by the manufacturer. Any unauthorized modification voids warranty.
