7.62 to 5.56 ejector. to 9mm hammer spring (maybe) and ejector for sure. It may or may not run well with the rifle hammer spring and might be a little harder to cock. Some use a .40cal spring and pretty much get away with everything. The registered pack my friend has that I run in my 9mm sometimes has a rifle hammer spring and all I have to do to use it is swap the ejectors and drop the pack in.
There are only two hammer springs. One for pistol and one for rifle. I have a rifle spring that is a bit shorter than normal, almost like they cut a winding off of it. I use it for every caliber. 9mm - .308 and it works fine.
I only change out the ejector lever when changing calibers. Also, I have found that the 53 and 33 ejector levers are interchangeable, even though the 53 is cut to a shorter length. I've used the factory 53 lever in my HK 93, C93 and V93. I've also used the HK33 lever in my V53 and CA53AR.
Ain't nobody going to blast you... well DJ or Retro might , but...
I use one of my sear packs completely set up for 223 and just change out the individual ejectors for whatever caliber from 9mm to 308. I have and leave in the rifle hammer spring for everything... even the 22 kit.
