1. The low power is usually the O-Ring installation process of the piston ran away, just reinstall it.

2. For the 4 screws of the spring cover, you need to judge the tightness, and you can't tighten it too tightly. It is more appropriate to leave the groove 1mm.
This is because of the water pipe cutting tolerance.
*The updated gasket is a softer foam, and there will be no problem of over-tightening and damaging the structure.

We spent 3 years designing this J-SPORT !
Recommend to everyone!

1: Is it normal that the O-Ring on the piston is loose?
A1: It is normal, the purpuse is to reduce resistance and increase speed.

Q2: Firing range of 1m, very little air.
A2. During the installation process, it is necessary to allow the piston and PVC to enter the body at the same time to avoid letting the piston O-Ring leave the PVC pipe to prevent the O-Ring from jumping out.

Q3: The velocity is only 80FPS.
A3: Please check whether the O-ring under the ammo cap is deformed.

Q4: Double feeding.
A4: This design uses vacuum tension to position the darts.Be sure to check the items below if you have this problem:

1. Silicone oil is not fully functioning, it can be improved by playing it a few times.
2. The pull rod is in place at a time, do not squeeze the air back and forth.
3. Reloading is indeed pressed to the end.
4. Do not use severely damaged darts.

Q5: Two XS screws are missing.
A5: This is what I forgot to ship in the first batch, the screws will be sended later on.
It will take a while. If you still want to finish G5 before getting the new screws, you can temporarily remove it from Urban Ops or buy it from a local store. This is the size: 2X6 pill TP

Q6: I broke the parts, can I apply for a replacement?
Q6: Please contact me for more information, Thank you!

Q7: How tight are the screws of the main spring cover?
Q7: ​Do not continue after stopping to avoid structural damage.

EZ comments:
There’s always a catch in triggers! So far there are some blaster which is hard to pull the trigger such as NYARF sharp-fire, Allpa strike Fang…etc, and you can’t tell from the outside. It’s not good designs for too hard to pull either too easy to pull, and you must have experienced it by yourself, that makes trigger just like the soul of blaster.
 
JSPB BattlePlanet G5 is designed for competitive sports, the trigger is following the standard of Olympics. There’s no delay while firing! Let’s enjoy the feeling of synchronizing with your blaster while firing!

It’s the less the better for 3D printed blasters, not like the puzzle which is the more the better. More 3D printed parts means more risk of malfunction and more deviation.
The main item of JSPB Planet G5 is one piece only, produced by industrial-grade 3D printer with optical axis made by German, chip made by Japan, as a high quality model without too many changeable parts, make it no burden to assemble!
