What they say
The first students are speaking.
"
★★★★★
"I've been in airsoft for 8 years and no one had explained the diagnosis this clearly to me. Module 1 alone has already saved me time and money on useless upgrades."
"
★★★★★
"I always used to stay quiet when they talked about internal mechanics. After module 3, I was the one who explained the Pro Build at the meetup. A whole new level."

Frequently asked questions
No fine print.
Yes. You get access to the first 3 modules without entering any payment information. If you want full access after completing them, you then pay €297. Otherwise, we don't charge you anything. There's no fine print.
No. Module 1 starts from a basic diagnosis—designed for someone who knows how to play but has never opened a replica. If you already have technical experience, Modules 3 and 4 will give you the system you were probably missing.
If within 7 days of purchase you don't feel it's worth the price, just let us know and we'll refund the full amount. No questions asked, no complicated forms. The risk is ours.
The price of €297 (instead of €497) is active until the launch quota is reached or the countdown timer you see above expires. When it closes, the price will revert to the standard price.
You've been looking at it for a while.
The first 3 classes are free. Within 48 hours, you decide if you want the rest.
