Nerf Nite Finder barrel insert

After replacing the spring in my nitefinder with a cut down C-836 (and removing the air restrictor), I found that while thicker darts fired fine, looser darts were struggling to fire in the unmodified barrel.

In the name of experimentation, I created an insert with a tighter barrel which pushed into the original, secured by press-fit.

This does introduce a ton of dead space, so I found that the original thick darts seemed to fire more slowly out of this insert, but it did help the thinner darts, albeit not by much.

Overall I wouldn't really say this is worth being a permanent fixture, more just a "nice to have" in the event that you have little control over what darts you have access to.

Some post-processing in the way of sanding down the barrel was necessary.

In conclusion: I'm just posting in case it's useful for a remix somewhere, or if someone else has a similar niche use case.

Incidentally, I found that using 70 degrees was a reasonable approximation/measurement
