Would this work?

[jaredu]

I have noticed that the rebel bottomline's ball detent is a little short and some balls fall right out, meaning double-feeding sometimes. So I took my old point zero's detent and put it in my rebel. It seems to fit, but I don't know if it will work when I'm playing. Please help!

i am pretty sure a spyder one would work right.

yeah my rebel had the same problem. I would point my gun down and the paintballs would just roll out. I got a new ball detent and it worked pretty well. In your rebel "fix it" pack that comes with your rebel, there is a spare ball; detent. THere are other things in there too. I think a spare trigger spring and some o-rings. If you can find this fix it pack that comes with your rebel u should be able to find the spare ball detent.

good luck

I put the spare detent on it and it was exactly the same.
