STRATOSPHERE /// Dart blaster tối ưu tốc độ

This is my first full blaster design, Stratosphere. It was created after I went to a couple games in urban environments with small flywheel blasters, giving me a much better idea of what I want when it comes to my favorite playstyle of carrying a ton of ammo, sprinting the entire time, and shooting anything that moves. This blaster was built specifically to feel ultra compact, able to hit anything between HvZ and 200fps, and have a decent number of modern features without breaking the bank. Oh, and be fast. :3

Features:
- Paintball style ergo (love it or hate it)
- Center of mass directly above the trigger face (with no battery)
- Semi auto solenoid pusher
- Multiple PCAR and battery box options
- Compact, it's small but feels even smaller than it looks
- Red dot mount underneath the picatinny rail
- Adjustable mag release to act like a normal release or a detent with a drop lever
- Full size wheels with support for anything up to manshees and quickdraws
- Adjustable, extremely clicky trigger capable of outrunning a neutron on 3s (best part lol)

I used to hate paintball ergo, since every paintball gun looks like a COD skin of the next. However, after trying it, I knew it was what I wanted to go with. It's just so compact, balanced, and easy to peek cover with. Speaking of balance, with the solenoid being directly above the trigger, this thing almost feels like you could spin it on your hand.

With the battery box being rectangular, it can be comfortably used as a support on the side or bottom of your forearm. I've included options for a straight mount and a 10 degree mount. The battery box has a small and large version, with the small version having an internal space of 28x44x100mm, and the large version being 34x54x120mm. I find both versions to be comfortably shoulderable, although the small box might be a bit short for anyone above 5'8". The battery door has 5mm of additional space so you don't have to squeeze your wires as hard. You can also not attach the battery box at all and just wire your battery through your shirt into a pocket or something.

I'm terrible at designing grips, so I remixed one of my open source favorites, the grip from the Gryphon. It's a similar story for the flywheel cage, however it now has slots for wheel alignment spacers. I've come to like the Gonk PCARs a lot, so I added support for them as well. At 30 feet the 3 line reduced my grouping with used darts by 2 inches in all directions and my fps by 5, and switching to the 6 line reduced the grouping by an additional 2 inches and the fps by an additional 3 on an HvZ setup.

Omg the trigger on this thing. Like, I know I'm the designer, but DAMN. It's super clicky and the pre travel and over travel can be adjusted to your liking, it's so spammable that I'm fairly easily able to outrun the neutron on 3s.

If you have any questions, want help with a build, have suggestions or feedback, just want to hear more about the blaster, want to sell these in some form, or anything else please message me on Discord @chickenmaster99! I also take commissions!

Various build notes:
This blaster supports Gonk geometry PCARs, which improve accuracy quite a bit. The files here only have 3 line and 6 line straight versions, but any Gonk compatible PCAR should fit.
You will need to use either a 3s or 4s lipo due to this using a neutron solenoid, so plan your flywheel setup accordingly.
Motor spanning boards will not fit on top of 180 size motors in this blaster.
The top rail is somewhat structural, so it should be replaced with the “RMR brace” when using a red dot.

There is a build guide pdf in the files, and the BOM can be found here, or linked in the build guide. There are several parts that you MUST USE BUTTON HEAD SCREWS FOR! SOCKET HEADS WILL NOT FIT!

Special thanks/credit to:
- Flygonial, for being the goat of open source flywheelers (some parts of this blaster started as Gryphon bits)
- Gonk, for the PCARs and flaring on the magwell
- Will (Beef) for the foregrip
- Closed beta testers Throttlepup321 and HoneyBea, and all the open beta testers
- Fourohfour, for giving me permission to make this even though it's basically a brushed Amoeba with a bunch of personal preference

“The trigger is money.” - Spencer ROC

Update 4/23/2025 - The holes in the magwell flaring were causing some hard mag insertions to feel icky, so they're just indents now

Update 4/30/2025 - Added a cage underbelly version without the foregrip

Update 8/24/2025 - Fixed the greebles on the cage not being centered

Update 9/6/2025 - Smoothed out some of the unnecessary edges on the frame, and added strength lines to the grip to force slicers to effectively generate 100% infill there

Update 4/15/2026 - Made the hexagons on the grip panels actually symmetrical between the left and right grip panels, also lowered the top edge a bit to make it easy to do filament swaps on the hexagons. Also fixed a heat insert hole not being as deep as it was supposed to be on the frame. Added newer versions of the gnk pcars.

Update 4/17/2026 - Made the friction fit on the muzzle slightly tighter, extended the back of the rev body back by 0.5mm to help the rev trigger as a whole wobble less once assembled, changed the rev body print orientation
