No, not off the top of my head. Specifically the Saint SBR had and uses a full top picatinny rail, where the pistol saint has a split picatinny top across of the handguard in theory making it easier to use a c-clamp grip. Now the new saints all have the full uninterrupted picatinny rail across the top. So do you want the uninterrupted top pic rail or full pic rail.
Also remember that you will also need the barrel nut, screws and locking plates.
