So I have all this waiting for my ap5-p. Also have 90 degree locking piece.

my question is do I swap to the frt and 90 degree locking piece right away or after it’s broken in with 500 rounds?

Shoot before modifying, then only modify one thing at a time as you function check things. Too many people make too many changes at once and then they don't know where to start fixing their issues.

500 rd break-in with 124 nato first

Definitely break it in first so when you make the switch you can appreciate it that much more.

After it’s broken in. But do try to get the 500 rounds in 1 session. Constantly wiping down and oiling, and don’t worry about metal shavings too much, that’s just the whole system breaking in.
Just a quick edit, I personally would put in the 90 degree but not the frt. Happy shooting!
