Playing with a syringe, a small spring a 5/2 and a bb of 6mm, plus a couple of hours in the afternoon. The result is not impressive but yes, very fun to do and shoot. Shoot with 80 psi :bounce:

Very nice! Is it a blow forward valve?

It is a common valve, of which they have for one side the two escapes and the supply of compressed air, and for the opposite side, the two exits. Too bad that support low pressure, up to 120 psi, but it is enough for this application. I need an exterior fairing with the look of a modern weapon, made of fiberglass or something similar.
Your design is excellent, and very simple. I had seen it and I like it.
He is connected in this way, he had already published it.

How do the BBs get into the Barrel? Via a sliding magazine over the barrel?

It was more or less like that, like in the drawing.
