Yes, don't run O-rings at all. DONE!

silveraider14 I've been contemplating swapping my front end components for those of another brand that is known for their precision but I'd likely need a few custom made components so I've not wanted to get into all that just yet. All I can say is that my 410 and my Son's RB5 are supremely precise compared to my 4.2. TLR Ball cups removed most of the slop, but some still remains from some of the parts.
