I've been starting work on a couple 15mm launcher projects but can't seem to find any specifications to help with design. The biggest thing I'm missing at the moment is the twist rate for the rifling. I could technically just use booleans from existing releases but would much rather have some more control over the geometry. Anyone have the specs?

I was going to attempt this method of measurement but figured it would be too inaccurate. However, I'd be satisfied rounding to the nearest half inch if someone could confirm the design uses an inch-based twist rate rather than a metric pitch.

    Tbh if I were you I'd make a projectile specific to the barrel you end up with using boolean cuts to eliminate the headache of recreating pre-existing stuff. Or you could always just use the existing screw on 15 barrels originally used on the pen15
