Do the 700mm crown barrel kits work on the FX Dreamline?

I might be wrong, I think I heard on the AEAC vlog if you 700 m barrel is meant for only the Crown Continuum (CC) series of the Crown. On the CC the barrels lock into the receiver with 4 “locking screws” vs. 2 as seen in the regular crown. Part of the reason for the 4 screws is to provide additional support needed to secure the 700 mm barrel into the receiver. I don’t know if this is the same set up as in the Dreamline and will work in the Dreamline. I am waiting on receiving my CC in .22 cal so I am trying to learn what I can about the gun.

I see. If possible, could you maybe try to see what happens if one is put on a Dreamline if you have one? If not, have you heard of any news of a 700mm barrel kit being made for the Dreamline?
