The MR Hop-Up 70° is a bucking designed for AEG replicas that need repeatable performance with heavier BBs. Its enlarged contact area promotes steady backspin and more consistent trajectories, particularly useful on precision-style rifles and tuned setups. An internal sealing/stabilization ring is built into the rubber; the inner barrel must include the perimeter cut required for proper seating and operation.

Warnings & safety information

Keep out of reach of children.

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

Do not tamper with the component: drilling, modifying or adapting the part voids warranty and may compromise safety and function.

The inner barrel must include the perimeter cut for the internal ring; without it the bucking will not seat correctly.

Avoid exposure to direct heat and aggressive solvents or chemicals that may degrade the rubber.

Dispose of following local waste regulations.

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

Usage instructions

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

Fit the bucking ensuring the internal ring seats into the barrel’s perimeter cut and the lip is correctly oriented.

Reassemble the hop-up unit carefully and perform test shots in a safe environment to adjust settings.

Do not force or damage the lip with improper tools.

Store dry at room temperature.
