The Super-BB That Never Took Off

However hard we pimp the replica – air drag is the one factor that will cap the BB’s range. But what if we pimp the BB too???

When Physics Won't Physicise

I'd always fantasized about a mighty physics simulator for an airsoft replica – that popular formula for the optimal barrel-to-cylinder volume ratio would miss by a fair bit in practice, and this way you could actually see what's really going on in there!

The Quiet zone for an even quieter replica

Experimenting with the simulator, I found a cylinder-volume zone where the piston lands softly and the slam gets noticeably quieter – at the price of a crumb of energy.
