View Full Version : Put an ACP bolt in -question

So I got the regular Delrin bolt from Alamo City (not the Low-Blo) and installed it today. But being a newb, I saw the little 6-pronged metal thing inside the stock bolt. The ACP bolt doesn't have one, does it serve a purpose? And what kind of oil do I need for the o-rings?

Are you talking about the star thing in the bolt? If so, that's the Venturi. It supposedly helps form even pressure around the paintball, but, it's not really needed and by taking it out it allows better air flow. And just use regular paintball specific gun oil. Just put a couple of drops in the ASA, air it up, dry-fire a couple of times and you should be good to go.
