Why this fuck is this thread still active.
Actually, the bows were spin-stabilized. The fletching made it spin in flight. And mass stabilization only increases the range, not accuracy. Tiny imperfections in the darts could have them going all over the place.
Every time this question comes up someone doesn't think it all the way through.
There are two types of stabilization of a projectile in motion... spin stabilization and mass stabilization. For example, the muskets that were first rifled to increase accuracy were firing round spheres of lead, which had terrible stabilization, so they needed to spin them in order to stabilize them in flight. On the other hand, a bow and arrow works by firing a very long, very front heavy projectile with a force at the rear end. This type of projectile doesn't need spin stabilization, and frankly it would be a waste of time, resources and energy. We properly weight our darts with 90% of the weight in front to naturally stabilize them in flight, since an object with weight near the front and a force at the back will be stable in flight.
There is absolutely no point in rifling a nerf barrel. PERIOD.
Bpso knows what he's talking about here. Stabilization = accuracy, genius. The thread should have ended after his response to this, but I get the feeling that people just wanted to repeat others to increase their e-dick size.
Anyway, a few months ago in a similar thread, Slug suggested the same thing Velveeta is talking about. It works to spin the dart - it could even be made to seal very well. It's still pointless, seeing as it has no advantages and many disadvantages (off the bat - weight, recharging, cost, moving parts to reliability, slower reload). Rifling or a spinning barrel setup with just foam (since you are trying to get some advantages, substituted for the other method of stabilization), the low overall mass and terrible aerodynamic form will have huge amounts drag and go no where. Anything heavier will just not be nerf anymore.
