4. What to do if BBs get jammed in the hop-up chamber?

BB jams in the hop-up chamber are often caused by poor-quality or dirty BBs, a folded hop-up bucking lip, or damage to the bucking itself.

Some of these issues can be fixed by yourself without sending the replica in for warranty repair.

If you hear a dull firing sound and no BB comes out of the barrel, a BB is most likely jammed in the hop-up chamber.

Use a cleaning rod to remove the stuck BB, then apply silicone spray to lubricate the bucking (insert the spray tube into the BB feed opening in the chamber).

After that, try to fire the replica and check if the problem is solved.

If the issue happens again, repeat the steps and use good-quality BBs (e.g. BLS).

If the problem persists, the next step is to remove the hop-up bucking.

Check if the bucking is damaged, clean it from dirt, lubricate it, and reinstall it correctly in the hop-up chamber.

If none of the above steps solve the BB jamming issue in the hop-up chamber, contact the Service Department.
