Three ways to get a custom build. Only one makes sense.
The big airsoft brands
Heavy, locked-in, costly to fix.
- —Proprietary parts and licensing

Closed platform
The DIY swamp
Free, until it isn't.
- —Mystery files from forums and YouTube
- —Parts that don't actually fit together
- —Hours of failed prints and re-orders
- —No help when it breaks at 11 PM
