Hey I have two questions.
I just purchased a lurker eigenbarrel, and was wondering it need an oring where you screw it in on the threads? I had a freak barrel for an ion and it had an oring right before the thread on the barrel.

And other question, not trying to turn this into a huge debate, but which is better underbore or over bore. The lurker eigenbarrel I got is .684 and the I use is .68 It fits tightly in the barrel (underbore) and does not roll out like my freak barrel which is overbore. Which is better? I was reading on another posts that underbore lowers accuracy and gives the ball a spin. Is this true?

Don't need an o-ring, just helps the barrel from coming loose, IF you have that issue. Not everyone does.

It's hard to perform conclusive tests on the effects of underboring or overboring. Since paintball sizes & conditions vary, and environmental conditions vary, there's really no way to determine which is better. My opinion: only underbore to prevent rollouts if you use closed-bolt guns and don't have a specific detent system for such a thing, and only overbore if you don't want a barrel kit. Kits are best to bore match, if that's your thing.

Alright, and seems like for boring I'll just have to choose between the stock and lurker before i get in a game to see which is better/i prefer. Thanks for the response!

Both underbore and overbore provide good shot to shot consistency. Underbore also provides you with great efficiency and overbore will give you a slightly lower risk of paint breaks in colder temperatures.

I tend to prefer underbore for everything except for extreme cases of weather or terrible paint. It allows you to run the lowest possible pressure on the gun for a better shot feel/quiet firing while giving you optimum air efficiency.
