On the RS sort of like the 51 there is no real standard on how they are made.
Mine is a Jeff Walters PCS build with a K carrier and RS length recoil rod. The very small number I have seen in person over the years all used custom RS length recoil rods as well.
I have never seen heard of anybody using a full size carrier with a reduced length K cocking tube support to make room for the longer full size MP5 carrier but I don't see any reason it wouldn't work. You are just changing out a custom length recoil rod for a custom cocking tube support.
It will be interesting to see how PTR decides to build these. One of my shooting buddies just bought one of these from Atlantic so should probably have it in hand in a week or so.
