【 Frequently Asked Questions 】

1. Is the assembly hole too tight to be inserted?

Slight hole expansion can be performed on the hole position, or appropriate polishing can be performed on the outer contour of the assembled parts.

2. Is the assembly hole too loose and inserted loose?

Assembly can be assisted with glue.

3. Can't bullets be fired smoothly?

Due to the horizontal printing of the bullets and to prevent them from easily falling out of the nose, the gap between the launch pipeline and the bullets is relatively small. The solution is as follows: Use sandpaper to polish the bullets, test while polishing, until the bullets can be fired smoothly (note: do not polish too much, otherwise the bullets will easily slide out of the machine head).

4. Is the range of the crossbow too close?

Please replace the bowstring material and tighten and shorten the length of the bowstring appropriately.

5. Can I play with children?

Once again, please do not give toys to minors to avoid personal injury accidents.

6. When launching, the nose always tilts up, making it impossible to release the bowstring for launch?

As shown in the figure below, you can use 2 rubber bands to bind the machine head and bow arm at the same time, which can effectively solve the problem of tilting the head.
