2023 CMP Service Pistol Rules (Sight Rib and Recoil Reduction)

Looking for some clarification on the new 2023 CMP rules.
  
1. Is a Bomar sight rib, with tuner, now acceptable to CMP on a service pistol for EIC? Saw something about a Rock River combo rib that got me wondering.  Seems like adding a rib of any kind would be an external modification and thus prohibited.  
2. Is a Sprinco two piece internal recoil reduction system that does not poke out in front of the dust cover and uses a solid recoil spring plug now prohibited by CMP on a service pistol for EIC?  It was considered internal and has been acceptable for years.  

Is this something Mr. Henderson of CMP will likely see and respond to on this forum or should CMP be emailed a query to respond to that could be posted on this forum?  Am getting back into Bullseye and am finding much has changed.

Ribs are fine so long a you make weight.

I would reach out directly to CMP Competitions on the springco thing.
