Funny you mentioned this... I have not even put a pod if any balls at all through those ss inserts ever since I got them lol
I was previously using a sniper barrel kit for my electro along with an etek4 shaft 4. Hopefully I will sell my sniper barrel kit tomorrow.
And there is also ion threads I need to worry about too... The problem with owning so many markers lol. The only freak barrel I even have now is one for my enmey
