If I'm not mistaken, there is only one size for the light sticks and caps because the inside of any color receiver is the same.

 

Oh hmm, I'll have to look into that but makes sense. They must not make the .284 in the 2.0 bc only one place sells the receivers and they don't say 2.0 so I'll need to find the 1.0 caps and hopefully any lite stick will fit.

The lite stick for the original omni brite and the omni brite 2 are the same. I changed out the original receivers and replaced them with the omni brite 2 receivers on some pro elite arrows and used the same light sticks. The caps are different though. If you can't find any original caps, I've got a few I will give you.

 

If you still need some of the original OmniBrite clear nock caps, please email TenPoint's Customer Service Department at info@tenpointcrossbows.com or call 330-628-9245 and choose Option 2 for Customer Service. They will be able to help you. Gwn001 is correct - the light sticks are the same and have not changed from OmniBrite to OmniBrite 2.0.

Good luck and happy hunting!
