there are no orings on an acs bolt. that is one of hte few reasons to change it. bolts with orings seal better and keeps blow back from happening

Its not supposed to have o-rings, the design doesn't work with o-rings. Why? The o-rings create drag if they seal well, the drag causes the acs bolt to compress as it moves forwards just enough so that it doesn't cup the ball, you'll get major blowby issues and possible unexplainable chops caused by turbulence.

Bandit Bolts Paintball sells delrin bolts with o-rings for low pressure and high pressure set-ups, that don't swell with oil. There are no ACS bolts with o-rings available from any manufacturer. Alamo also has o-ring bolts made from delrin. Check out my review of the Bandit:

There are 2 types of ACS.....plastic and metal. Maybe the one you saw w/the o-ring was made of metal -

The drawing that Kingman sends out with the 05 Pilot ACS is of the Pilot. It does not have an ACS bolt. If you look closely at the drawing you will notice a few other differences; bolt, trigger frame, barrel and drop forward are all different.
