This blaster uses a bolt-magazine interlock, meaning the bolt must be pulled back before the magazine can be inserted or removed.
If you’re new to this type of system, or don’t use it often, please make a habit of removing the magazine when handling or storing the blaster at home — especially when other people are around!!!
This type of mechanism can be easy to mishandle if you’re not familiar with it, so a simple “mag out when not in use” habit can help prevent mistakes.
We highly recommend checking the accessory installation guide on this page after purchase.
The S100S-S Bai Ze is the latest Fully Upgraded version of ZWQ’s S100S, and this is the version that finally got us interested in the platform.
The big one is the 188cc air cylinder. Pair that with a seriously strong structure, and the S100S-S gives you plenty of room to play with different springs, barrels and darts without immediately running into the limits of the blaster itself.
And that’s really what we like about it.
For our testing, we used our own sourced 2.0mm × 17mm × 305mm spring, ZWQ’s 600mm inner barrel, and Worker Bambu 1.2g 3-ring darts.
With no BCAR installed, we recorded 380+ FPS.

For something shooting at this level, the prime is surprisingly reasonable. The side-bolt setup gives you good leverage, and we don’t find the 2.0 spring particularly difficult to prime.
There’s definitely more available if that’s what you’re after. Some players have tuned their S100S builds to around 440 FPS. We haven’t tried to chase that number ourselves, and for now we don’t plan to stock anything heavier than the 2.0 spring.
We also pulled one apart for a closer look, and you can see our teardown photos in the gallery. While doing that, we removed the small damping spring in front of the plunger head. With it out, the plunger has a little more travel and therefore a little more air volume. Since it was already apart, we put it over the chronograph again:


We asked ZWQ whether running it like this would be an issue, and their answer was that it should be fine given the metal internal structure.
We’re only showing the result here, not suggesting this is the setup everyone should run. More air isn’t necessarily better — it still needs to work with the barrel length, bore size, darts and the rest of the setup.
With a blaster like this, the setup matters just as much as the blaster.
Different springs, barrel lengths, barrel bore sizes, darts and BCARs can give very different results. There isn’t one combination that makes sense for everyone, especially once you start playing around at these speeds.
That’s why the 188cc cylinder matters. It gives you plenty of air to work with, while the strong S100S-S structure gives you a solid base to build your setup around.
There aren’t many springers playing comfortably in this kind of territory without moving into much more expensive full-CNC blasters.
The S100S-S takes a simpler approach: a massive 188cc cylinder, a structure strong enough to handle serious power, and plenty of room for the player to tune from there.
ZWQ also uses the S100S-S for testing its Ling Kong bearing BCAR, including extensive testing around the 400 FPS level. That was one of the things that originally made us take a closer look at this version.
Once our first batch arrived, we tested one ourselves. The combination of the build, the 188cc cylinder and the amount of tuning room made the decision pretty easy — we ordered another batch before the first one was even listed.
For us, that’s the appeal of the S100S-S. The blaster is already strong enough. Now you get to decide what you want to do with it.
Upgrade spring is not included. We don’t have one spring configuration that we consider the right default for the S100S-S, so we’ve left the choice to the player.
