Well I just yanked my prechambers.

First off.. these tools are top rate. I've got a large 1/2" craftsman socket wrench. I think the ring removal tool feels more solid than the wrench.

I was a little sloppy taking the first ring off and didn't make sure the tool was snug and did a good job of ripping the ring up. However, I'm sure its still usable, just be carefull.

The slide hammer is a beast. It only took about 10-15 slams to get the prechambers free.

I'm a little concerned about the adpater that fits in the prechamber. It wouldn't thread all the way in, and as a result I pulled out the first thread on a couple of my prechambers. I'll see how the injectors seat before I re-install them.
